Citation Code Reference Table Atlas
Original research draft · October 2026
Expanded original research draft edition. Research cutoff: October 8, 2026.
These tables were independently authored for Citation Code from the primary sources identified beside each table. Their selection, columns, examples and explanations are original. They are not a conversion of another manual's table rows.
Three kinds of content are kept distinct: a source fact identifies what an official publication actually calls or numbers; a Citation Code house choice states this book's preferred presentation; a fictional training object supplies stipulated facts for a completed example. Receiving court, journal, instructor or employer requirements take priority over a house choice.
Every record marked TRAIN is fictional. Its people, titles, dates, page numbers, document numbers, quotations and crosswalks are invented for instruction; it is not a reported case or real evidence. Real statutes, publications, courts and historical opinions are identified by their official sources. Reserved example.com addresses are demonstration addresses.
The research cutoff is October 8, 2026. An edition year or historical rulemaking date identifies a consulted version; it does not establish that no later amendment, correction or treatment exists. These selected tables do not claim exhaustive jurisdictional coverage or decide a source's controlling force.
Read the when-to-use sentence before using a row. Its first columns identify the object and the needed coordinate; its final column explains the ambiguity the construction resolves. Use the linked chapters for the surrounding rule or workflow.
The atlas contains 24 tables and 305 rows. Each AT label is a reader-facing table number; the corresponding table-atlas-* anchor is its stable digital destination. Each data row also has a stable identifier in the companion JSON for future indexing and maintenance.
- AT01. Identify the publication before choosing its citation form
- AT02. Separate an opinion's name, date, reporter, page and speaker
- AT03. Federal circuit identity: preserve the institution, then shorten clearly
- AT04. Court names that lose meaning when shortened too far
- AT05. Constitutional coordinates without invented subdivisions
- AT06. Complete statutory pinpoints from the 2024 Code
- AT07. One enacted law, several identifiers: keep each coordinate in its system
- AT08. Annual CFR snapshots: the year does not supply the month
- AT09. Federal Register fields that answer different questions
- AT10. Congressional measure types: the prefix is part of the identity
- AT11. Federal bill-version codes: carry the stage with the text
- AT12. Attribute legislative material to the component that actually speaks
- AT13. Record locators: name the object and the coordinate together
- AT14. Transcript and errata coordinates: preserve the original exchange
- AT15. A completed record-to-appendix crosswalk
- AT16. Books and articles: choose the component's actual locator
- AT17. Web and archive objects: locate the representation you actually used
- AT18. A date register that separates publication, revision and legal events
- AT19. Selected geographic codes: recognize postal fields without turning them into court names
- AT20. Citation Code month forms and machine-date components
- AT21. Roles, publication components and subdivisions: a compact house vocabulary
- AT22. Selected reporter and opinion identifiers: read the token before normalizing it
- AT23. Numbers, symbols and ranges: completed transformations that preserve meaning
- AT24. Treaties, international institutions and arbitral texts: identify the right object
AT01. Identify the publication before choosing its citation form
When to use: Use when a search result, PDF cover, or database label gives you several plausible source names. The row identifies the publication object you actually possess; it does not certify the authority of a proposition in it.
Scope: United States federal publication systems and selected New York reporting sources. Facts concern container identity. The construction decisions are Citation Code editorial defaults.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| What you possess | Identity to record | Coordinate that travels with it | Construction decision |
|---|---|---|---|
| Supreme Court bound opinion PDF beginning at printed 662 | United States Reports, volume 556; Ashcroft v. Iqbal | 556 U.S. 662; use the supporting printed page as the additional pinpoint | A PDF file is a delivery format; it does not replace the reporter identity. |
| Supreme Court preliminary print, volume 577, part 1 | United States Reports preliminary print; volume and part | Keep the volume/part publication stage in the source record | Confirm the final pagination before replacing a slip citation with a bound-volume form. |
| Page-proof volume bearing the Court's watermark | United States Reports page proof | Preserve the displayed volume and page numbers, plus proof status | Do not remove the proof label merely because the PDF comes from the Court. |
| 2024 section download from the USCODE collection | United States Code, 2024 edition | Title, section, subdivisions, and 2024 version | The filename's repository hierarchy is not an extra statutory subdivision. |
| Public Law 117-2 pamphlet | American Rescue Plan Act of 2021, slip law | Public-law number; act section; 135 Stat. page | A cover leaf does not turn viewer page 1 into the act's first printed page. |
| A law inside Statutes at Large volume 135 | Chronological enactment publication | Volume 135 and printed page; retain law/act identity when useful | Do not substitute the later code section for an enactment-history claim. |
| 2024 annual CFR volume | Code of Federal Regulations annual snapshot | Title, section, edition year and revision date in the source record | An October download does not change a January revision date. |
| April 20, 2026 Federal Register document | Federal Register publication of a particular agency document | Volume 91, beginning page 20902, publication date and document type | Distinguish the document's agency text from adjacent material on the same printed page. |
| BILLS-117hr1319enr | H.R. 1319, 117th Congress, enrolled version | Chamber/measure number, Congress and enrolled stage | The suffix identifies the version; it is not a statutory section. |
| A committee report from the CRPT collection | House, Senate, executive or conference report | Report series and number, Congress, part if present, pinpoint | A committee report number is not the number of its associated bill. |
| A hearing PDF from the CHRG collection | Particular committee hearing publication | Committee, hearing title/date, witness or component and printed page | A witness statement is attributed to that witness, not silently to the entire committee. |
| A daily Congressional Record page beginning with H | House section of the daily Congressional Record | Volume, H-prefixed page and issue date | Keep the prefix; H123 and S123 are different coordinates. |
Use the publication's own identity even when a commercial or public database supplied the copy. A provider name can identify an access route without becoming the author.
A source register may preserve more metadata than the final citation. Preserve fields needed to distinguish two versions even when a particular receiving rule does not print every field.
Primary sources and their scope: Supreme Court: U.S. Reports publication guide; GPO United States Code guide; GPO Statutes at Large guide; GPO Public and Private Laws guide; GPO Code of Federal Regulations guide; GPO Federal Register guide; GPO Congressional Bills guide; GPO Congressional Reports guide; GPO Congressional Hearings guide; GPO Congressional Record guide; New York Law Reporting Bureau publications; Ashcroft v. Iqbal, official U.S. Reports PDF; DOJ 2026 compliance-date interim final rule.

AT02. Separate an opinion's name, date, reporter, page and speaker
When to use: Use while transferring case metadata into a citation or replacing a slip reference. These completed fields show why adjacent numbers and headings do different work.
Scope: Historical source-identity facts from three official Supreme Court PDFs. This table neither summarizes holdings nor supplies subsequent-treatment conclusions.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Source field | Completed fact | Use in the reference | Error the distinction prevents |
|---|---|---|---|
| Iqbal reporter identity | 556 U.S. 662 (2009) | Volume 556; United States Reports; beginning printed page 662; decision year 2009 | Treating 556 as a docket number or 662 as the pinpoint for every proposition. |
| Iqbal docket number | No. 07-1015 | Store as a separate case-identity field | Changing the decision year to 2007 because the docket begins with 07. |
| Iqbal argued date | December 10, 2008 | Record the argument event if the research concerns argument | Using the argument date as the decision date. |
| Iqbal decision date | May 18, 2009 | Record the decision event; use 2009 in this reporter example | Mistaking the October Term 2008 heading for the decision year. |
| Iqbal beginning page | Printed 662 | Preserve 662 in the full reporter citation | Replacing the beginning page with the passage pinpoint and losing the case's opening coordinate. |
| Iqbal passage at printed 678 | 556 U.S. 662, 678 (2009) | Use 678 for the identified passage in the Court's opinion | Citing viewer page 17 as reporter page 17. |
| Iqbal Souter writing | Souter dissent begins at printed 687 | Identify Souter's dissent when using that writing | Treating all pages of one case PDF as majority reasoning. |
| Iqbal Breyer writing | Breyer dissent begins at printed 699 | Keep the speaker/writing qualifier with a pinpoint such as 700 | Assigning a dissent's discussion to the Court. |
| Brown beginning page | 347 U.S. 483 (1954) | Volume 347 and first printed page 483 identify this reported decision | Reusing 483 as a substantive pinpoint without reading the passage. |
| Brown printed page 495 | 347 U.S. 483, 495 (1954) | Preserve beginning page 483 and supporting page 495 as separate fields | Replacing a volume/page pair with a PDF index. |
| Marbury parallel volume naming | 5 U.S. (1 Cranch) 137 (1803) | Preserve the nominative reporter information where the receiving form calls for it | Treating 5 U.S. and 1 Cranch as two different cases. |
| Marbury supporting printed page | 5 U.S. (1 Cranch) 137, 177 (1803) | The pinpoint is 177 in the printed report | Converting a scan's image sequence into an unverified reporter pinpoint. |
The Iqbal PDF's first printed page is 662, so printed 678 is viewer page 17 in that particular 39-page file. That arithmetic is file-specific; it is not a rule for other scans.
Abbreviated case names here are Citation Code display choices. Caption details, procedural roles and complete publication metadata remain in the research record.
Primary sources and their scope: Ashcroft v. Iqbal, official U.S. Reports PDF; Brown v. Board of Education, official U.S. Reports PDF; Marbury v. Madison, official U.S. Reports PDF.
Related sections: 4.4 Handle neutral citations and slip opinions; 5. Find the Exact Supporting Passage; 18. Slip Opinions, Neutral Citations, and Separate Writings; E01. A correct case identity with the wrong pinpoint; E02. Correcting a dissent attributed to the Court.
AT03. Federal circuit identity: preserve the institution, then shorten clearly
When to use: Use when a docket export, caption, or research note says only a number or a place. The selected location helps distinguish institutions; it is not an appellate-jurisdiction test.
Scope: Circuit names and selected geographic examples drawn from 28 U.S.C. § 41 in the 2024 edition. This is not a complete current territory/routing table. The shortened labels are Citation Code house labels, subject to receiving requirements.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Issuing institution | Citation Code short label | Selected identity check | Do not infer |
|---|---|---|---|
| United States Court of Appeals for the First Circuit | First Circuit | Puerto Rico appears with Maine, Massachusetts, New Hampshire and Rhode Island in § 41 | A Puerto Rico source is not necessarily a Commonwealth-court source. |
| United States Court of Appeals for the Second Circuit | Second Circuit | New York is a listed component jurisdiction | The New York Court of Appeals is a different institution. |
| United States Court of Appeals for the Third Circuit | Third Circuit | New Jersey and the Virgin Islands appear in the statutory composition | A numbered state appellate department is not this federal circuit. |
| United States Court of Appeals for the Fourth Circuit | Fourth Circuit | Maryland and Virginia are listed component jurisdictions | Maryland's former Court of Appeals is not the federal Fourth Circuit. |
| United States Court of Appeals for the Fifth Circuit | Fifth Circuit | Louisiana, Mississippi and Texas are listed components | The word Texas alone does not identify this court rather than a Texas state court. |
| United States Court of Appeals for the Sixth Circuit | Sixth Circuit | Kentucky, Michigan, Ohio and Tennessee are listed components | A local court called Circuit Court is not a federal court of appeals. |
| United States Court of Appeals for the Seventh Circuit | Seventh Circuit | Illinois, Indiana and Wisconsin are listed components | A Seventh Judicial District is not this circuit. |
| United States Court of Appeals for the Eighth Circuit | Eighth Circuit | Minnesota and Missouri are listed component jurisdictions | A location clue does not establish which appeal route applies to a specialized matter. |
| United States Court of Appeals for the Ninth Circuit | Ninth Circuit | California, Guam and Hawaii appear in the statutory composition | Do not derive a complete territorial-jurisdiction map from this selected example. |
| United States Court of Appeals for the Tenth Circuit | Tenth Circuit | Colorado, New Mexico and Oklahoma are listed components | A state Tenth District label is not interchangeable with this circuit. |
| United States Court of Appeals for the Eleventh Circuit | Eleventh Circuit | Alabama, Florida and Georgia are listed components | A federal district court in one of those states is not the court of appeals. |
| United States Court of Appeals for the District of Columbia Circuit | D.C. Circuit | The official court masthead includes United States and Circuit | Do not shorten it to D.C. Court of Appeals. |
| United States Court of Appeals for the Federal Circuit | Federal Circuit | Section 41 describes its territorial composition as all federal judicial districts | Nationwide composition does not mean every federal appeal goes there. |
For compact parentheticals, a receiving rule may prescribe labels such as 1st Cir. or D.C. Cir. This table's ordinary-language labels do not override those instructions.
The 2024 statutory composition text contains historical wording, including a Canal Zone reference. The table deliberately supplies selected identity checks rather than presenting that text as a cleaned current jurisdiction map.
Primary sources and their scope: 28 U.S.C. § 41, 2024 edition; United States Court of Appeals for the District of Columbia Circuit.
Related sections: 2. Establish the Receiving Requirements; 17. Case Names, Courts, and Reporter Identity; 23. Bankruptcy, Tax, Immigration, and Specialist Forums; Court Gateway Atlas.
AT04. Court names that lose meaning when shortened too far
When to use: Use before replacing a full court name with Supreme Court, Court of Appeals, Appellate Court or a state abbreviation. Retain the level and branch that distinguish the actual institution.
Scope: Selected New York, Maryland, Texas and federal institutions. Names and structural descriptions are source facts; the suggested retained labels are editorial decisions. No exhaustive state survey is claimed.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Document's institution | Retain in the source record | Completed distinguishing label | Why the extra words matter |
|---|---|---|---|
| New York Court of Appeals | New York; Court of Appeals | New York Court of Appeals | This is the state's highest court, although its name does not say Supreme. |
| New York Supreme Court, trial level | New York; Supreme Court; county when supplied | New York Supreme Court, Kings County | Omitting the county and trial-level context can invite an incorrect highest-court assumption. |
| New York Supreme Court, Appellate Division | New York; Appellate Division; department | Appellate Division, First Department | The department distinguishes the branch; Supreme Court alone obscures appellate identity. |
| New York Supreme Court, Appellate Term | New York; Appellate Term; applicable department/district description | Appellate Term, Second Department | Appellate Term and Appellate Division are different institutional labels. |
| Maryland Court of Appeals before the rename | Historical court name appearing on the decision | Court of Appeals of Maryland (historical name) | A historical record should remain searchable under the name printed when it issued. |
| Supreme Court of Maryland after the rename | Supreme Court of Maryland; relevant date | Supreme Court of Maryland | Use the historical name on an older decision rather than silently modernizing the court identification. |
| Maryland Court of Special Appeals before the rename | Historical intermediate appellate name | Court of Special Appeals of Maryland (historical name) | Removing Special can turn the old intermediate-court name into the old highest-court name. |
| Appellate Court of Maryland after the rename | Appellate Court of Maryland; relevant date | Appellate Court of Maryland | Its post-rename label differs from Supreme Court of Maryland. |
| Supreme Court of Texas | Texas; Supreme Court | Supreme Court of Texas | The October 2026 chart assigns final civil and juvenile appellate jurisdiction here. |
| Texas Court of Criminal Appeals | Texas; Court of Criminal Appeals | Texas Court of Criminal Appeals | The same chart places final criminal appellate jurisdiction in this separate court. |
| Texas Fifteenth Court of Appeals | Texas; Fifteenth Court of Appeals | Fifteenth Court of Appeals of Texas | The October 2026 chart distinguishes its statewide role from the regional First–Fourteenth courts. |
| United States Court of Appeals for the D.C. Circuit | United States; District of Columbia Circuit | D.C. Circuit | Dropping Circuit and United States erases the federal institutional identity. |
Maryland's December 7, 2022 notice states that preexisting case numbers do not change merely because the appellate courts are renamed. Keep the number printed in the actual case record.
Structural descriptions identify a tribunal. They do not decide whether a particular disposition is precedential, appealable, citable or controlling.
Primary sources and their scope: New York Court System Outline; New York Courts: Appellate Courts; Maryland Judiciary appellate-court name-change notice; Texas court structure chart, October 2026; United States Court of Appeals for the District of Columbia Circuit.

AT05. Constitutional coordinates without invented subdivisions
When to use: Use when a proposition identifies a constitutional clause or amendment by a familiar name. Construct the coordinate from the actual hierarchy and retain the amendment/article distinction.
Scope: United States Constitution and ratified amendments, using National Archives transcriptions. Locators identify text; they do not state the present doctrinal scope of a constitutional right or power.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Text being identified | Completed Citation Code locator | Hierarchy to preserve | Boundary |
|---|---|---|---|
| Commerce clause text in Article I | U.S. Const. art. I, § 8, cl. 3 | Article; section; clause | Clause 3 is not amendment III. |
| Necessary and Proper Clause text | U.S. Const. art. I, § 8, cl. 18 | Article I; section 8; final numbered clause | Do not shorten to section 18. |
| Presidential oath text | U.S. Const. art. II, § 1, cl. 8 | Article II; section 1; clause 8 | The article numeral remains II even when a source displays modern headings. |
| Judicial power text | U.S. Const. art. III, § 1 | Article III; section 1 | Do not invent a numbered paragraph for an unnumbered transcription passage. |
| Article III case categories | U.S. Const. art. III, § 2, cl. 1 | Article III; section 2; clause 1 | An explanatory website heading is not part of the constitutional hierarchy. |
| Supremacy Clause text | U.S. Const. art. VI, cl. 2 | Article VI; clause 2 | Article VI has no numbered section 2 in this construction. |
| First Amendment | U.S. Const. amend. I | Amendment I | Do not assign an official section number to the unsectioned amendment. |
| Fourth Amendment | U.S. Const. amend. IV | Amendment IV | A sentence or phrase description may narrow discussion without inventing section 1. |
| Fifth Amendment | U.S. Const. amend. V | Amendment V | A named protection within the amendment is not automatically a separately numbered clause. |
| Thirteenth Amendment, first section | U.S. Const. amend. XIII, § 1 | Amendment XIII; section 1 | Preserve the section because section 2 is a separate provision. |
| Fourteenth Amendment, first section | U.S. Const. amend. XIV, § 1 | Amendment XIV; section 1 | A locator to the whole amendment is broader than a locator to section 1. |
| Twenty-Sixth Amendment, first section | U.S. Const. amend. XXVI, § 1 | Amendment XXVI; section 1 | Preserve the Roman numeral rather than silently converting it to Article XXVI. |
The National Archives Bill of Rights page also explains the original proposed articles. For a citation to a ratified amendment, use its ratified amendment number rather than the proposal's position.
Article and clause numbering may be supplied as conventional navigation labels even where the engrossed original is not printed as a modern numbered outline. Confirm the passage, not merely the label.
Primary sources and their scope: National Archives Constitution transcription; National Archives Amendments 11–27; National Archives Bill of Rights transcription.

AT06. Complete statutory pinpoints from the 2024 Code
When to use: Use to check whether a pinpoint stops too early or silently changes a letter, case or nesting level. The examples are coordinates to the identified 2024 compilation, not conclusions about a live dispute.
Scope: Selected provisions of titles 5 and 17 in the 2024 United States Code. Citation Code chooses the display form; the underlying subdivision labels are source facts.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Needed coordinate | Completed reference | What the last element selects | Repair to reject |
|---|---|---|---|
| FOIA request provision | 5 U.S.C. § 552(a)(3)(A) (2024) | Lettered subparagraph A inside paragraph 3 of subsection a | § 552(3)(A) drops an actual hierarchy level. |
| FOIA fee-award subparagraph | 5 U.S.C. § 552(a)(4)(E)(i) (2024) | Lowercase Roman clause i inside uppercase E | § 552(a)(4)(e)(1) substitutes different characters. |
| FOIA judicial-order alternative | 5 U.S.C. § 552(a)(4)(E)(ii)(I) (2024) | Uppercase Roman subclause I inside clause ii | Stopping at E conceals which alternative is being discussed. |
| FOIA voluntary-change alternative | 5 U.S.C. § 552(a)(4)(E)(ii)(II) (2024) | Uppercase Roman subclause II | Repeating subclause I points to different text. |
| FOIA first exemption | 5 U.S.C. § 552(b)(1) (2024) | Paragraph 1 of subsection b | (a)(1) is another location, not an interchangeable abbreviation. |
| FOIA definition subsection | 5 U.S.C. § 552(f) (2024) | The complete subsection f | Do not add a paragraph number unless the particular definition is identified. |
| Reproduction-right clause | 17 U.S.C. § 106(1) (2024) | Numbered clause 1 | § 106(a)(1) invents a lettered level absent from this provision. |
| Sound-recording performance clause | 17 U.S.C. § 106(6) (2024) | Numbered clause 6 | The digit 6 is a clause number, not a statutory page. |
| First fair-use factor | 17 U.S.C. § 107(1) (2024) | First numbered factor | A pinpoint to (1) does not represent all four factors. |
| Second fair-use factor | 17 U.S.C. § 107(2) (2024) | Second numbered factor | Preserve (2), even if an excerpt presents factors as bullet points. |
| Third and fourth fair-use factors | 17 U.S.C. § 107(3)–(4) (2024) | Two adjacent numbered factors | Do not use (3)(4), which falsely suggests nested levels. |
| Section 109, subsection a | 17 U.S.C. § 109(a) (2024) | Subsection a | A whole-section reference is broader and should not masquerade as this pinpoint. |
The parenthetical 2024 identifies the consulted compilation. It does not say the provision was enacted in 2024 or that later law has been checked.
A citation to a numbered factor or exception establishes where its text is located. Applying that text requires the surrounding provision and relevant law.
Primary sources and their scope: 5 U.S.C. § 552, 2024 edition; 17 U.S.C. § 106, 2024 edition; 17 U.S.C. § 107, 2024 edition; 17 U.S.C. § 109, 2024 edition.

AT07. One enacted law, several identifiers: keep each coordinate in its system
When to use: Use when a bill, a public-law PDF, a Statutes at Large page, a code note and a code provision all appear in one research trail. This actual publication chain shows which number belongs to which object.
Scope: American Rescue Plan Act of 2021 historical publication identity. The table does not analyze eligibility, payments, expiration, subsequent amendments or current tax treatment.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Research object | Completed identity or location | Meaning of the coordinate | Citation decision |
|---|---|---|---|
| House measure | H.R. 1319, 117th Congress | 1319 is a House bill number within the 117th Congress | Do not write Public Law 1319. |
| House-passed publication | BILLS-117hr1319eh | EH identifies the engrossed House version | Name the stage when discussing that text rather than later enacted language. |
| Senate-amendment publication | BILLS-117hr1319eas | EAS identifies an engrossed Senate amendment | Keep the amendment version distinct from the House text. |
| Enrolled publication | BILLS-117hr1319enr | ENR identifies the enrolled measure | Its bill-page numbering does not become Statutes at Large pagination. |
| Enacted law number | Pub. L. No. 117-2 | 117 identifies the Congress; 2 identifies this public law | Do not treat the hyphenated pair as a section range. |
| Enactment date on the law | March 11, 2021 | The date is printed with the public-law identification | A later PDF production timestamp is not the enactment date. |
| Law's opening printed page | 135 Stat. 4 | 135 is the Statutes at Large volume; 4 is the beginning page | The PDF's unnumbered cover precedes this printed page. |
| Short-title provision | Pub. L. No. 117-2, § 1, 135 Stat. 4, 4 (2021) | Act section 1 supplies the short title | The repeated page 4 is intelligible: first page and pinpoint coincide. |
| Act section adding a Code provision | Pub. L. No. 117-2, § 9601(a), 135 Stat. 4, 138 (2021) | Act section 9601(a) begins the insertion of Internal Revenue Code § 6428B | Do not write 26 U.S.C. § 9601 merely because 9601 appears in the act. |
| Inserted provision label | Internal Revenue Code § 6428B, inserted by § 9601(a) | 6428B belongs to the amended Code; 9601 belongs to the amending act | Cite the act for the historical insertion, then separately identify any Code version actually used. |
The source's § 9601(a) and the provision it adds are nested in different documents. Copying only the nearest bold section heading can swap the two systems.
A marginal classification note is a navigation aid. It should not replace the actual act section when the claim concerns what Congress enacted in that act.
Primary sources and their scope: American Rescue Plan Act of 2021 slip law; H.R. 1319, 117th Congress, enrolled version; H.R. 1319, 117th Congress, engrossed House version; H.R. 1319, 117th Congress, engrossed Senate amendment; GPO Public and Private Laws guide; GPO Statutes at Large guide; GPO United States Code guide.

AT08. Annual CFR snapshots: the year does not supply the month
When to use: Use when selecting or describing an annual Code of Federal Regulations volume. The completed dates apply the publisher's stated revision cycle to a 2024 snapshot label.
Scope: Annual CFR publication cycle, illustrated with selected 2024 title-year combinations. These are revision-cutoff facts, not assertions that a provision stayed unchanged afterward. Individual volume availability and text must still be checked.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Selected annual snapshot | Revision cutoff represented | Record this version fact | Do not substitute |
|---|---|---|---|
| Title 1, 2024 annual CFR | January 1, 2024 | 2024 edition, revised as of January 1 | October 8, 2026, merely because that is the research date. |
| Title 5, 2024 annual CFR | January 1, 2024 | Title 5 belongs to the titles 1–16 cycle | A January publication date guessed from a downloaded filename. |
| Title 17, 2024 annual CFR | April 1, 2024 | Title 17 begins the titles 17–27 cycle | January 1, a cutoff used by a different title group. |
| Title 21, 2024 annual CFR | April 1, 2024 | Retain April 1 with the annual edition in the source record | An eCFR current-through date from a different representation. |
| Title 28, 2024 annual CFR | July 1, 2024 | Title 28 begins the titles 28–41 cycle | June 24, 2024, an effective date appearing in a particular rule. |
| Title 29, 2024 annual CFR | July 1, 2024 | Preserve July 1 even when the file was acquired later | A source website's footer year. |
| Title 37, 2024 annual CFR | July 1, 2024 | Use the annual snapshot's cutoff for version identification | A patent application's filing date. |
| Title 40, 2024 annual CFR | July 1, 2024 | Record the title and individual volume as well as the cutoff | A volume number used as though it were a section number. |
| Title 44, 2024 annual CFR | October 1, 2024 | Title 44 belongs to the titles 42–50 cycle | July 1, the cutoff for the preceding title group. |
| Title 50, 2024 annual CFR | October 1, 2024 | The same calendar year can contain four different revision cutoffs | December 31, which the annual cycle does not imply. |
A regulation may change after an annual volume's revision cutoff. For an event-specific question, follow the publication and effective-date trail rather than treating the edition year as a full-year guarantee.
The title-year examples teach the revision schedule; they are not a claim that every volume file was downloaded or that every section within a title was reviewed.

When to use: Use when a rulemaking page mixes a document number, docket, RIN, publication date, effective date, compliance date, explanation and amendatory text. Keep them as separate fields before writing the citation.
Scope: DOJ's April 24, 2024 final rule and April 20, 2026 interim final rule, read as historical publication records. Later changes or litigation are outside this table. Original 2024 compliance dates must not be presented as current deadlines.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Field or document | Completed fact | What it identifies | Construction consequence |
|---|---|---|---|
| 2024 publication coordinate | 89 Fed. Reg. 31320 (Apr. 24, 2024) | Volume, first printed page and publication date | These fields find the published document. |
| 2024 issuing component | Civil Rights Division, Department of Justice | Agency attribution printed with the document | Do not attribute the rule to GovInfo merely because GovInfo hosts the PDF. |
| 2024 action label | Final rule | Document type in the published action field | Do not relabel it a proposed rule because it discusses earlier comments. |
| 2024 CFR destination | 28 C.F.R. part 35 | Codification destination named in the document | Part 35 is not Federal Register page 35. |
| 2024 regulatory identifier | RIN 1190-AA79 | Regulatory Information Number | Retain in research metadata; do not use as a page pinpoint. |
| 2024 rule effectiveness | June 24, 2024 | Effective date stated on the first page | Keep distinct from the April 24 publication date. |
| Original 2024 larger-entity compliance date | April 24, 2026, as stated in the 2024 document | A historical compliance date for the specified category | Label it historical because the 2026 document amends compliance dates. |
| 2026 publication coordinate | 91 Fed. Reg. 20902 (Apr. 20, 2026) | Volume, beginning printed page and date | Page 20902 also contains adjacent Treasury material; locate the DOJ heading. |
| 2026 action label | Interim final rule and request for comments | The published DOJ document type | An invitation for comments does not by itself make this a proposed rule. |
| 2026 effective date | April 20, 2026 | Effective date stated in that document | Do not derive effectiveness from when the PDF was downloaded. |
| 2026 explanatory passage | Printed 20908 | Agency explanation within the 2026 document | Use the explanatory pinpoint for the agency's stated reason, not as the location of every amendment. |
| 2026 amendatory text | Printed 20912; amendments to § 35.200(b)(1)–(2) | Text changing April 24, 2026 to April 26, 2027, and April 26, 2027 to April 26, 2028 | Preserve both category-specific substitutions; do not compress them into one undifferentiated deadline. |
A completed source citation can be historically accurate while a sentence about present duties is wrong. This table demonstrates field separation, not an October 2026 compliance opinion.
When a multi-column PDF begins midway down a printed page, confirm the agency heading before attributing the page's first extracted lines to the document you intend to cite.
Primary sources and their scope: DOJ 2024 web-accessibility final rule; DOJ 2026 compliance-date interim final rule; GPO Federal Register guide.
Related sections: 10. Cite Regulations, Rules, and Agency Materials; 22. Regulations, Guidance, and Administrative Decisions; 52. Rulemaking Sources: From Proposal to Operative Paragraph; E08. A rulemaking publication whose compliance dates later changed.
AT10. Congressional measure types: the prefix is part of the identity
When to use: Use when transcribing a measure from a search result or constructing a research query. Preserve chamber and measure type before adding a number, Congress and version.
Scope: The eight federal measure types identified in GPO's bill collection guide. This table identifies document types; it does not state enactment requirements, legal force, or procedural consequences for a particular measure.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Displayed prefix | Completed type identity | Metadata token used by the collection | Practical distinction |
|---|---|---|---|
| H.R. | House bill | hr | Keep H.R. rather than changing it to H. Res.; they are different measure types. |
| S. | Senate bill | s | A Senate bill number can coincide with a House bill number without identifying the same measure. |
| H.J. Res. | House joint resolution | hjres | Preserve Joint; deleting it changes the type. |
| S.J. Res. | Senate joint resolution | sjres | Preserve both Senate and joint-resolution identity. |
| H. Con. Res. | House concurrent resolution | hconres | Concurrent is a type field, not a committee name. |
| S. Con. Res. | Senate concurrent resolution | sconres | The prefix distinguishes it from S.J. Res. with the same number. |
| H. Res. | House simple resolution | hres | Do not insert a Joint label merely because the subject concerns another chamber. |
| S. Res. | Senate simple resolution | sres | Retain the Congress in a full record because numbers recur across Congresses. |
H.R. 1319, 117th Congress, and the publication token hr1319 describe the same measure identity at different display levels. The version suffix supplies an additional field, not a replacement for the Congress.
A collection token is useful for retrieval. Citation Code does not require readers to print a repository's entire package ID in every conventional citation.
Primary sources and their scope: GPO Congressional Bills guide.
Related sections: 21. Bills, Legislative History, and Congressional Materials; 51. Legislative Materials: Attribution, Stage, and Source Form; AT11 — Federal bill-version codes: carry the stage with the text.
AT11. Federal bill-version codes: carry the stage with the text
When to use: Use when multiple files share a bill number but contain different wording. This is a recognition table for selected GPO version codes; it is not a claim that every listed stage occurred for a particular bill.
Scope: Selected publisher-defined version codes. The completed stage labels are source metadata facts. The retention decisions are Citation Code practices, subordinate to a receiving authority's form.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Version token | Stage identity | What to retain in a source record | Completed decision |
|---|---|---|---|
| IH | Introduced in House | House introduction stage and the document's own date | A comparison using IH must not silently label its text as enacted. |
| IS | Introduced in Senate | Senate introduction stage and the document's own date | Keep IS distinct from IH even when two companion bills have similar titles. |
| RH | Reported in House | House reported stage; any accompanying report identity separately | A reported bill and a committee report are separate documents. |
| RS | Reported in Senate | Senate reported stage and the actual text | Do not replace it with a later floor version without revising the analysis. |
| EH | Engrossed in House | House-passed version | H.R. 1319's actual EH file is distinct from its enrolled file. |
| ES | Engrossed in Senate | Senate-passed version | The chamber is part of the version description. |
| EAH | Engrossed amendment in House | House amendment text and the underlying measure | An amendment document may instruct changes rather than reproduce a clean consolidated bill. |
| EAS | Engrossed amendment in Senate | Senate amendment text and the underlying measure | H.R. 1319's actual EAS file is not the EH text under another filename. |
| ENR | Enrolled | Enrolled measure and its publication identity | H.R. 1319 ENR is still a bill-publication object, distinct from Pub. L. No. 117-2. |
| RDS | Received in Senate | Senate receipt stage | Receipt is a different recorded stage from passage. |
| RFH | Referred in House | House referral stage | A referral label does not identify the receiving committee unless the document supplies it. |
| RFS | Referred in Senate | Senate referral stage | Preserve the text's stage rather than guessing from the latest bill-status display. |
Only the H.R. 1319 EH, EAS and ENR files were used as actual stage examples in this atlas. The other rows identify codes from the publisher's guide and do not fabricate a publication history.
For a quotation, compare the exact selected version. A bill-status timeline can confirm that an event occurred without supplying the wording used in every version.
Primary sources and their scope: GPO Congressional Bills guide; H.R. 1319, 117th Congress, engrossed House version; H.R. 1319, 117th Congress, engrossed Senate amendment; H.R. 1319, 117th Congress, enrolled version.

AT12. Attribute legislative material to the component that actually speaks
When to use: Use after finding a report, hearing or Record extract. Locate the speaker or component before converting a sentence into a statement about what Congress found or intended.
Scope: Every completed packet and reference in this table is an ORIGINAL FICTIONAL TRAINING OBJECT. The official GPO guides support only the distinctions between publication types and components. TRAIN references are not citations to real congressional records.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Stipulated TRAIN packet fact | Completed reference fragment | What the source can be described as | Claim to revise |
|---|---|---|---|
| TRAIN House Committee Report HR-12, majority discussion on printed 8, dated May 4, 2025 | TRAIN House Committee Report HR-12, at 8 (May 4, 2025) | The committee report's majority discussion | Congress conclusively determined the fact. |
| The same packet places minority views on printed 19 | TRAIN House Committee Report HR-12, at 19 (minority views) | The identified minority views | The report unanimously states the proposition. |
| TRAIN Hearing HE-12, May 6, 2025, witness Lila Arden's oral answer on printed 42 | Lila Arden testimony, TRAIN Hearing HE-12, at 42 (May 6, 2025) | A named witness's testimony | The committee found what the witness said. |
| Arden's prepared statement begins on printed 51; passage on 53 | Lila Arden prepared statement, TRAIN Hearing HE-12, at 53 | The witness's submitted prepared statement | The transcript shows this sentence was spoken at the hearing. |
| A post-hearing answer from Arden is printed on 71 and dated May 13, 2025 | Lila Arden supplemental answer, TRAIN Hearing HE-12, at 71 (May 13, 2025) | A later written answer reproduced in the hearing publication | The witness gave this answer during the May 6 session. |
| TRAIN report contains a TRAIN Transit Office letter at appendix B, printed 88, dated April 30, 2025 | TRAIN Transit Office letter, April 30, 2025, reproduced in TRAIN Report HR-12, app. B, at 88 | An agency letter reproduced by the report | The report's authors wrote the letter. |
| TRAIN floor extract FE-12 identifies Senator Vale, printed S24, June 2, 2025 | Senator Vale statement, TRAIN Floor Extract FE-12, at S24 (June 2, 2025) | One identified speaker's statement | The Senate adopted every statement on the page. |
| TRAIN House extract FE-13 identifies Representative Neri, printed H24, same date | Representative Neri statement, TRAIN Floor Extract FE-13, at H24 (June 2, 2025) | A different chamber's extract | Page 24 alone distinguishes the two records. |
| TRAIN extension extract EX-12, June 2, 2025, contains a submitted statement at E9 | TRAIN Extension Extract EX-12, at E9 (June 2, 2025) | Material printed in an extension section | The page itself proves the statement was delivered orally. |
| TRAIN digest DG-12, June 2, 2025, summarizes activity at D3; underlying vote extract is FE-14, H31, from the same date | TRAIN Digest DG-12, at D3; TRAIN Floor Extract FE-14, at H31 (June 2, 2025) | A summary and a separate underlying record | The digest substitutes for the vote text when the precise recorded wording matters. |
The fictional prefixes S, H, E and D deliberately exercise the source's coordinate types. They are not assertions that a real Congressional Record issue contains these training statements.
For a real hearing, its session date and later publication date can differ. Preserve both when the difference explains how the material entered the record.
Primary sources and their scope: GPO Congressional Reports guide; GPO Congressional Hearings guide; GPO Congressional Record guide.
Related sections: 21. Bills, Legislative History, and Congressional Materials; 51. Legislative Materials: Attribution, Stage, and Source Form; 43.4 Quote inside a parenthetical only when the wording matters.
AT13. Record locators: name the object and the coordinate together
When to use: Use when litigation materials contain several numbering systems. Each row supplies the facts needed to produce its reference fragment. A fragment becomes filing-ready only after the receiving record convention and the complete case identity are supplied.
Scope: All rows are ORIGINAL FICTIONAL TRAINING OBJECTS in TRAIN Case R-13. They demonstrate Citation Code record descriptions. FRAP 28(e) and Civil Rule 56(c) provide contextual reasons to identify specific record material; they do not prescribe these exact labels.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Stipulated record facts | Completed locator fragment | Coordinate being used | Meaning preserved |
|---|---|---|---|
| Complaint filed April 2, 2026; docket entry 4; allegation in numbered paragraph 17 | Complaint ¶ 17, TRAIN Case R-13, docket entry 4 (Apr. 2, 2026) | Source-assigned paragraph | Identifies an allegation; it does not convert that allegation into evidence. |
| Answer filed April 22, 2026; entry 9; response to paragraph 17 | Answer ¶ 17, TRAIN Case R-13, docket entry 9 (Apr. 22, 2026) | Answer paragraph 17 | The matching number refers to a different document from Complaint ¶ 17. |
| Neri declaration dated May 3, 2026; entry 22-1; statement in paragraph 6 | Neri declaration ¶ 6, docket entry 22-1 (May 3, 2026) | Declaration paragraph | The attachment number is separate from paragraph 6. |
| Motion memorandum filed May 4, 2026; entry 22; passage at printed 12 | Motion memorandum 12, docket entry 22 (May 4, 2026) | Document's printed page | A brief's assertion retains its character as advocacy. |
| Exhibit C to the Neri declaration; stamped TRAIN-NERI-000047 | Neri declaration, Ex. C, TRAIN-NERI-000047 | Exhibit label and complete production stamp | Leading zeros belong to the identifier and remain intact. |
| Exhibit C, page stamped TRAIN-NERI-000047, screenshot panel B | Neri declaration, Ex. C, TRAIN-NERI-000047, panel B | Stamp plus within-page panel | Panel B narrows the passage without replacing the document identity. |
| Hearing transcript dated May 8, 2026; printed 76, lines 3–11 | Hearing transcript 76:3–11 (May 8, 2026) | Transcript page and line numbers | The colon separates page from line rather than denoting a time. |
| Audio hearing file AH-13, May 8, 2026; event at elapsed 00:18:42–00:19:03 | TRAIN Audio AH-13, 00:18:42–00:19:03 (May 8, 2026) | Elapsed media position | The reference does not claim this position is a certified transcript page. |
| Order entered May 12, 2026; docket entry 31; direction in paragraph 4 | Order ¶ 4, docket entry 31 (May 12, 2026) | Order's own numbered paragraph | An entry number identifies the filing, not the passage. |
| Email from Inez Vale to Omar Pell, exhibit E; sent March 9, 2026 at 14:08 UTC; stamp TRAIN-MAIL-0081 | Email from Inez Vale to Omar Pell, Mar. 9, 2026, 14:08 UTC, Ex. E, TRAIN-MAIL-0081 | Message identity plus exhibit stamp | The citation identifies the sent message rather than a later forwarding wrapper. |
| TRAIN Intake Workbook, spreadsheet exhibit F; version 2; sheet Intake; cell D47 | TRAIN Intake Workbook, version 2, sheet Intake, cell D47, Ex. F | Workbook version, sheet and cell | D47 on another sheet or version is not the same coordinate. |

In a filed appellate brief, material reproduced in the appendix may require the appendix coordinate rather than this internal working reference. Use the receiving rule and the final crosswalk.
A locator can accurately identify an allegation, disputed exhibit, or unsworn statement. Its specificity does not settle admissibility or evidentiary weight.

AT14. Transcript and errata coordinates: preserve the original exchange
When to use: Use when a transcript, condensed copy, errata sheet and recording all refer to the same examination. Keep the original coordinate stable while explaining the version or speaker actually used.
Scope: ORIGINAL FICTIONAL TRAINING OBJECTS. Mira Sol's deposition was taken June 4, 2026 in TRAIN Case D-14. Every page/line, erratum and media time below is stipulated. Rule 30(e)–(f) is context for reviewing changes; this table does not decide whether a particular change is valid or admissible.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Stipulated fact | Completed locator fragment | What remains distinct | Correction to make |
|---|---|---|---|
| Certified transcript page 41, lines 7–12 | Sol deposition 41:7–12 (June 4, 2026) | Original transcript page and line | Do not cite the condensed PDF's viewer page 12 as transcript page 12. |
| Question begins at 41:7; answer continues through 42:3 | Sol deposition 41:7–42:3 (June 4, 2026) | Both full page/line endpoints | 41:7–3 is ambiguous and drops the second page. |
| Answer at 42:8–11 depends on question at 42:5–7 | Sol deposition 42:5–11 (June 4, 2026) | The answer's qualifying question | Expand the range when quoting the answer alone would conceal its scope. |
| Attorney objection appears at 43:4–6; witness answer at 43:7–10 | Sol deposition 43:7–10; see also 43:4–6 (June 4, 2026) | Counsel's speech and witness's speech | Attribute the objection to counsel rather than placing it in the witness's quotation. |
| Signed errata sheet dated June 19, 2026, item 2, addresses 41:10 | Sol deposition 41:10; Sol errata item 2 (June 19, 2026) | Original answer and separate change record | Do not silently replace the transcript text with the erratum. |
| Errata item 2 replaces Tuesday with Thursday and gives a calendar-review reason | Sol errata item 2 (June 19, 2026) (changing the day stated at 41:10) | Changed wording and stated reason | A corrected day is not proof of every surrounding event. |
| Errata item 3 withdraws a change to 44:2 | Sol errata item 3 (June 19, 2026); Sol deposition 44:2 | The withdrawal and original passage | Do not retain a superseded proposed correction in the final quotation. |
| Officer's certificate dated June 4, 2026 on unnumbered terminal leaf, identified in packet as certificate C-1 | Sol deposition, officer's certificate C-1 (June 4, 2026) | Certification component | Do not assign it a fictitious transcript page 99. |
| Recording file SOL-A, elapsed 01:06:12–01:06:29, corresponds to 41:7–12 | TRAIN Recording SOL-A, 01:06:12–01:06:29; Sol deposition 41:7–12 | Time coordinate and transcript coordinate | A time-to-line crosswalk is additional packet evidence, not a mathematical page conversion. |
| A revised certified transcript dated June 24, 2026 renumbers the passage to 42:1–6 | Sol revised deposition 42:1–6 (certified June 24, 2026; examination June 4, 2026) | Examination date and revised certification/version date | Update citations after checking the new page map rather than changing only the date. |
For an errata comparison, preserve the certified original, signed change list, stated reasons and relevant certificate. Rule 30's conditions and the treatment of substantive changes require separate legal review.

AT15. A completed record-to-appendix crosswalk
When to use: Use after assembly changes move material. This table demonstrates exact remapping and records omitted items rather than guessing a nearby appendix page.
Scope: ORIGINAL FICTIONAL TRAINING PACKET A-15. The first column identifies source coordinates; the old and final columns are stipulated assembly maps. Citation Code uses App. as a defined training label. The receiving court's required label and record rules control.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Source coordinate | Superseded draft appendix | Final assembled appendix | Citation/release action |
|---|---|---|---|
| Complaint ¶ 17, printed 6 | Draft App. 12 | App. 18 | Replace 12 with 18; retain the complaint identity in the source crosswalk. |
| Answer ¶ 17, printed 4 | Draft App. 24 | App. 31 | Do not borrow the complaint's new page because paragraph numbers coincide. |
| Neri declaration ¶ 6, printed 2 | Draft App. 41 | App. 52 | Update the declaration reference to App. 52 after opening that final page. |
| Exhibit C, stamp TRAIN-NERI-000047 | Draft App. 48 | App. 61 | Confirm the full stamp at 61; insertion of a cover sheet changed the offset. |
| Sol deposition 41:7–12 | Draft App. 75 | App. 92 | If the receiving form permits line detail, use App. 92 (Sol deposition 41:7–12). |
| Sol deposition 41:20–42:3 | Draft App. 75–76 | App. 92–93 | Preserve both appendix pages and the original page/line span in the mapping record. |
| Sol errata item 2 | Draft App. 80 | App. 98 | Move the errata reference separately from the transcript reference. |
| Order ¶ 4, printed 3 | Draft App. 101 | App. 126 | Regenerate every short reference that depends on the order's former page. |
| Email exhibit E, TRAIN-MAIL-0081 | Draft App. 110 | Not reproduced in final appendix | Flag as absent; apply the receiving rule's route for unreproduced record material. |
| Audio SOL-A, elapsed 01:06:12–01:06:29 | Draft attachment note at 121 | Final attachment index at App. 140; audio remains separate | Cite the recording through the authorized record route; the index page alone is not the recording. |
The final mapping is not created by applying one global offset. Different insertions and omissions changed the documents by different amounts.
FRAP 28(e) distinguishes material in the appendix from specified original-record or unreproduced material and addresses contested evidence. This training map does not replace those alternatives with a universal App. format.

When to use: Use when a publication has an editor, chapter author, article number, separately numbered supplement, preprint or rolling update. The completed references preserve the distinction that makes the cited passage retrievable.
Scope: All named works and identifiers in this table are ORIGINAL FICTIONAL TRAINING OBJECTS. Crossref guidance supports only the treatment of a genuine assigned DOI as a persistent link; no registered DOI is invented. Titles follow Citation Code's italic-title default.

Where a source lacks a title, label an authored description as a description instead of inventing a publication title.
A capture records what was preserved. Authenticity, completeness and the legal significance of a historical representation require separate assessment.

AT18. A date register that separates publication, revision and legal events
When to use: Use before reducing several source dates to a single parenthetical year. Record the event first, then decide which date the reader needs for the stated proposition.
Scope: ORIGINAL FICTIONAL TRAINING PACKET V-18. All dates and effects are stipulated for this exercise; they are not real statutory deadlines or agency rules. Official publication guides support the distinction between date fields, not the fictional legal effects.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Stipulated event | Stored date and event label | Reader-facing description | Date to keep separate |
|---|---|---|---|
| TRAIN Instruction I18 signed on January 8, 2026 | 2026-01-08 / signed | TRAIN Instruction I18, signed Jan. 8, 2026 | Publication on January 12. |
| The same instruction was published January 12, 2026 | 2026-01-12 / published | TRAIN Instruction I18, published Jan. 12, 2026 | Its signature date. |
| The packet expressly makes the instruction effective February 1, 2026 | 2026-02-01 / effective | TRAIN Instruction I18, effective Feb. 1, 2026 | Publication does not supply this distinct event. |
| The packet sets first required compliance at April 1, 2026 | 2026-04-01 / compliance | TRAIN Instruction I18, compliance date Apr. 1, 2026 | The February effective date. |
| A correction signed January 20 changes a word without changing the stipulated effective date | 2026-01-20 / correction signed | TRAIN Correction C18 (Jan. 20, 2026), correcting I18 | The date of the corrected instruction is not overwritten. |
| TRAIN compiled manual CM18 includes amendments through March 15, 2026 | 2026-03-15 / incorporated through | TRAIN Compiled Manual CM18, incorporating amendments through Mar. 15, 2026 | The manual's release on March 22. |
| The compiled manual was released March 22, 2026 | 2026-03-22 / released | TRAIN Compiled Manual CM18 (released Mar. 22, 2026) | Incorporated-through date remains March 15. |
| Researcher downloaded CM18 on October 8, 2026 | 2026-10-08 / acquired | Source register: acquired Oct. 8, 2026 | Acquisition does not update the manual's substantive coverage. |
| TRAIN Contract C18 signed June 2, 2026, states an effective date of May 1, 2026 | 2026-06-02 / signed; 2026-05-01 / stated effective | TRAIN Contract C18 (signed June 2, 2026; stated effective May 1, 2026) | This label reports the instrument; it does not resolve enforceability. |
| TRAIN Hearing H18 occurred July 7, 2025; printed volume issued February 2026 | 2025-07-07 / hearing; 2026-02 / publication month | TRAIN Hearing H18 (July 7, 2025), published Feb. 2026 | Do not convert a publication month into a day-specific date. |
| TRAIN judgment entered August 14, 2026; amended opinion O18 issued August 28, 2026 | 2026-08-14 / judgment; 2026-08-28 / amended opinion | TRAIN Amended Opinion O18 (Aug. 28, 2026) | Judgment entry and opinion revision are different events. |
| TRAIN article was posted December 18, 2025; volume imprint is 2026 | 2025-12-18 / online publication; 2026 / volume imprint | Record both; identify the consulted version in the reference | Do not silently choose whichever year seems more recent. |
Use a null or an explicit month-only field when a day is unknown. January 1 is not a neutral stand-in for an unknown date.
If a date controls the legal analysis, prove the event and its consequences from the relevant source. The citation's date label alone does not calculate a filing period or establish retroactivity.

AT19. Selected geographic codes: recognize postal fields without turning them into court names
When to use: Use when importing a government address, institution record or spreadsheet containing a two-letter location field. Expand that field before deciding whether a court or legal-publication abbreviation is appropriate.
Scope: Selected USPS two-letter postal mappings, verified October 8, 2026. These are postal identifiers, not a complete legal-geography table or a prescription for citation parentheticals. Citation Code normally retains full geographic names unless an established source or receiving rule requires another form.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Geographic name | USPS postal code | Distinction to preserve | Editorial use |
|---|---|---|---|
| Alabama | AL | Different from Alaska's AK | Expand AL to Alabama in the source register before identifying a court. |
| Alaska | AK | Different from Alabama's AL | The final letter is K, not the state's last letter. |
| Arizona | AZ | Different from Arkansas's AR | Preserve the Z when importing an address field. |
| Arkansas | AR | Different from Arizona's AZ | Do not normalize both states to a guessed Ariz./Ark. field. |
| California | CA | A United States postal field here, not an unqualified country code | Identify the coding system before expanding CA. |
| Colorado | CO | A location field here, not company as a word abbreviation | Do not apply a case-name company abbreviation to a postal value. |
| District of Columbia | DC | A geographic identifier rather than the D.C. Circuit court name | Add the institution's actual name to identify a tribunal. |
| Georgia | GA | The United States postal designation, not a country-name determination | Preserve the field's United States address context. |
| Guam | GU | Its own postal identifier | A postal code does not by itself choose a court or appellate route. |
| Maine | ME | Different from Maryland's MD and Massachusetts's MA | Expand the two-letter value exactly. |
| Maryland | MD | Different from a professional degree abbreviation in a person's name | Interpret the value through its field and document context. |
| Massachusetts | MA | Different from Maine's ME | Do not infer a court abbreviation from the postal code alone. |
| Michigan | MI | Different from Minnesota's MN and Mississippi's MS | Keep the complete state name in identity metadata. |
| Minnesota | MN | Different from Michigan's MI | Transposition can change the jurisdiction rather than merely its spelling. |
| Mississippi | MS | Different from Missouri's MO | Never use the first two printed letters of the full name as a guessing rule. |
| Missouri | MO | Different from Montana's MT | A recognized postal mapping is preferable to guessed expansion. |
| Montana | MT | Different from Missouri's MO | The code is a structured field, not a citation-style choice. |
| Nebraska | NE | The same letters can signify northeast in a directional field | Keep state and direction fields separate. |
| Northern Mariana Islands | MP | The code does not reproduce the name's initial letters | Preserve MP when the supplied data schema is USPS postal coding. |
| Puerto Rico | PR | Its own postal identifier | Do not use the location field to infer federal versus Commonwealth court identity. |
| Washington | WA | Distinct from District of Columbia DC | Washington without institutional context can be ambiguous. |
| West Virginia | WV | Distinct from Virginia VA | Do not drop West during name compression. |
These rows answer a narrow decoding problem. A postal list does not establish political status, court jurisdiction or a legal citation's required abbreviation.
When a source uses a different code system, such as a publisher's court code, its own documented mapping controls. Never apply this postal mapping merely because the field has two letters.

AT20. Citation Code month forms and machine-date components
When to use: Use for compact citation dates after the source's month, day, year and event have been identified. Full month names remain the default in ordinary prose.
Scope: Original Citation Code house choices matching section 47.5. The twelve dates are fictional formatting demonstrations, not assertions that a document or legal event occurred. GPO's manual is publication-design context only and does not govern these choices.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Full month | Compact Citation Code form | Month component | Completed formatting example |
|---|---|---|---|
| January | Jan. | 01 | Jan. 8, 2026; machine date 2026-01-08 |
| February | Feb. | 02 | Feb. 8, 2026; machine date 2026-02-08 |
| March | Mar. | 03 | Mar. 8, 2026; machine date 2026-03-08 |

| August | Aug. | 08 | Aug. 8, 2026; machine date 2026-08-08 |
| September | Sept. | 09 | Sept. 8, 2026; machine date 2026-09-08 |
| October | Oct. | 10 | Oct. 8, 2026; machine date 2026-10-08 |
| November | Nov. | 11 | Nov. 8, 2026; machine date 2026-11-08 |
| December | Dec. | 12 | Dec. 8, 2026; machine date 2026-12-08 |
Do not append a period to May, June or July under this house convention. A receiving rule may use a different abbreviation, including a different treatment of September.
The machine date is a storage example. A month-only source dated May 2026 remains month-only; the table does not authorize inventing a day.

Related sections: 47.5 Label dates by the event they describe; AT18 — A date register that separates publication, revision and legal events.
AT21. Roles, publication components and subdivisions: a compact house vocabulary
When to use: Use when a short label can save space without erasing who wrote the material or which component contains the passage. The example fragments contain explicitly fictional TRAIN materials except the general role labels.
Scope: Original Citation Code display choices, with the official Iqbal PDF supplying real examples of separate judicial writings and GPO/NY manuals supplying publication context. This table is not a universal abbreviation mandate. All TRAIN names, works and coordinates are fictional.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.

| Translator | trans. | TRAIN Register Study 18 (Mira Sol trans., 2026) | A translated passage may differ from the original-language text. |
| Edition | ed. after the edition number | TRAIN Register Study 18 (3d ed. 2026) | ed. after 3d means edition; after a person's name it can identify editor. |

| Dissenting judicial writing | dissenting, spelled out | TRAIN Opinion O21, at 9 (Vale, J., dissenting) | A dissent qualifier reports the speaker's position; it is not optional when attribution depends on it. |
| Concurring judicial writing | concurring, spelled out | TRAIN Opinion O21, at 7 (Neri, J., concurring) | A concurrence should not be labeled the court's majority reasoning. |

| Acting official | retain Acting in the name/role when material | Acting Director Mira Sol, TRAIN Direction D21 (June 8, 2026) | Dropping Acting can misdescribe the capacity identified by the source. |
A defined document label can remain roman while a substantive publication title is italicized. These examples follow the title rule in section 46.1.
No entry authorizes inventing a chapter, paragraph, footnote, issue or institutional title. Use the label that the actual source supplies before applying a house abbreviation.

AT22. Selected reporter and opinion identifiers: read the token before normalizing it
When to use: Use when a citation import has removed punctuation, merged digits, or confused a publication with a court. This table recognizes selected series; it does not assign a fabricated reporter citation to any training case.
Scope: Selected publication identities checked against official Supreme Court materials and the New York Law Reporting Bureau. NY-style token spellings are explicitly observed forms, not a nationwide display mandate. Series recognition does not establish precedential value.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Observed token or form | Publication or identifier | Identity field to retain | Practical parsing decision |
|---|---|---|---|
| U.S.; US in NY-style display | United States Reports | Reporter identity distinct from volume and first page | 556 U.S. 662 uses 556 as volume and 662 as opening page. |
| 1 Cranch; paired with 5 U.S. in Marbury | Nominative reporter volume within early United States Reports | Both the nominative and U.S. volume identities when the form needs them | Do not create two case records merely from the parallel volume naming. |
| F3d in the NY reporting manual | Federal Reporter, Third Series | Third-series marker | Do not parse 3d as part of the first page. |
| F4th in the NY reporting manual | Federal Reporter, Fourth Series | Fourth-series marker | A conversion to F3d would change publication identity. |
| F Supp 3d in the NY reporting manual | Federal Supplement, Third Series | Supplement and third-series fields | Removing Supp turns the token into a different reporter family. |
| Fed Appx in the NY reporting manual | Federal Appendix | Complete series identity | Appx here is part of a reporter name, not the brief's appendix. |
| NY | New York Reports, first series | Reporter family and absence of a later-series suffix | Do not infer a postal field solely from the letters NY. |
| NY2d | New York Reports, Second Series | Second-series marker | Keep 2d attached to the reporter token rather than the volume. |
| NY3d | New York Reports, Third Series | Third-series marker | Do not expand it as a New York Third Department court identifier. |
| App Div | Appellate Division Reports, first series | Reporter series | App Div in a reporter field does different work from a court-name field. |
| AD2d | Appellate Division Reports, Second Series | Series 2d | AD2d does not mean Appellate Division, Second Department. |
| AD3d | Appellate Division Reports, Third Series | Series 3d | AD3d does not identify the Third Department. |
| Misc | Miscellaneous Reports, first series | Complete series identity | Misc is not permission to omit the court or source identity. |
| Misc 2d | Miscellaneous Reports, Second Series | Second-series marker and spacing appropriate to the chosen system | Keep it distinct from Misc 3d even if volume/page numbers coincide. |
| Misc 3d | Miscellaneous Reports, Third Series | Third-series marker | The final digit identifies the reporter series, not a judicial department. |
| NY Slip Op | New York Slip Opinion Service identifier | Year, complete assigned decision identifier and any printed status suffix | An electronic identifier is not automatically a volume/page reporter citation. |
Recognition and presentation are different operations. Preserve a normalized internal identity, then render punctuation and spacing required by the receiving system.
A source's unofficial or nonprecedential label requires its own legal/status analysis. This table supplies no blanket permission to cite a decision merely because a reporter token was recognized.
Primary sources and their scope: Supreme Court: U.S. Reports publication guide; Ashcroft v. Iqbal, official U.S. Reports PDF; Marbury v. Madison, official U.S. Reports PDF; New York Law Reports Style Manual, 2022 with 2024 electronic update; New York Law Reporting Bureau publications.

AT23. Numbers, symbols and ranges: completed transformations that preserve meaning
When to use: Use in a final citation pass where automatic formatting is likely to change a coordinate. First identify whether the characters are a quantity, a range, a source-assigned label or a machine identifier.
Scope: Original Citation Code house constructions consistent with chapter 47. All TRAIN coordinates are fictional. Publisher manuals are contextual references rather than authority imposing these house choices.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Stipulated source or draft | Citation Code output | Meaning retained | Transformation to reject |
|---|---|---|---|
| TRAIN printed passage begins at 503 and ends at 504 | 503–504 | Full inclusive page endpoints | 503–04 under this house default. |
| TRAIN passage spans printed 129 through 131 | 129–131 | Hundreds digit remains visible | 129–31 when the receiver has not required shortened endpoints. |
| TRAIN relevant pages are 17 and 23, with no reliance on intervening pages | 17, 23 | Two discrete locations | 17–23, which falsely asserts a continuous cited range. |
| TRAIN paragraph range begins at 8 and ends at 11 | ¶¶ 8–11 | Multiple numbered paragraphs | ¶ 8-11 as though it were one source-assigned label. |
| TRAIN section coordinates are 4.2, 4.3 and 4.4 | §§ 4.2–4.4 | Full decimal section endpoints | §§ 4.2–4, which can change the endpoint. |
| TRAIN section 7 has nested statutory-style labels (a)(3)(B) and (a)(3)(C) | § 7(a)(3)(B)–(C) | Shared hierarchy with explicit final sibling endpoints | § 7(a)(3)(B)(C), which makes C appear nested within B. |
| TRAIN passage includes § 7(a) and § 8(c), not every intervening provision | §§ 7(a), 8(c) | Two distinct provision selections | §§ 7(a)–8(c), which overstates the range. |
| TRAIN transcript lines 5 through 12 on page 41 | 41:5–12 | Page 41; lines 5–12 | 41.5–12 or 41:05:12, which resembles another coordinate system. |
| TRAIN transcript starts 41:20 and ends 42:3 | 41:20–42:3 | Full cross-page endpoints | 41:20–3, which loses the second page. |
| TRAIN looseleaf printed page is literally 4-22 | 4-22 | Source-assigned composite page label | 4–22, which turns the label into a range. |
| TRAIN production stamp is A000047 | A000047 | Prefix and leading zeros | A47, which may identify another item or no item. |
| TRAIN front-matter page is xii | xii | Roman pagination | 12, which may identify an Arabic-numbered body page. |
| TRAIN media segment is elapsed 1 hour, 2 minutes, 8 seconds through 1 hour, 2 minutes, 31 seconds | 01:02:08–01:02:31 | Hours, minutes and seconds at both endpoints | 1:2–31, which obscures units and endpoints. |
| TRAIN measured interval is eleven calendar days | 11 calendar days | A measured quantity in numerals under the house default | Treating the spelling eleven as part of a source-assigned identifier. |
Full range endpoints do not mean repeating every shared statutory hierarchy component. The output must preserve the endpoint's level and make the range unambiguous.
The choice of en dash for a range does not authorize changing hyphens inside docket numbers, production stamps, rule numbers, page labels or exact quotations.
Primary sources and their scope: GPO Style Manual, 2016 edition; FRAP 28 on the Fourth Circuit official rules site.
Related sections: 47.1 Preserve the source's coordinate system; 47.2 Display inclusive ranges with full endpoints; 47.3 Preserve nested divisions and repeated symbols; 47.4 Treat identifiers differently from quantities; 47.6 Distinguish clock time, duration, and media position.
AT24. Treaties, international institutions and arbitral texts: identify the right object
When to use: Use when a treaty text, depositary status page, institution's rule set, resolution and judgment appear in the same research trail. The completed identities prevent an acronym or series number from standing in for the source actually used.
Scope: Selected primary institutional records inspected October 8, 2026. Historical treaty/judgment identifiers and rule-set versions only. No exhaustive international abbreviation table, treaty-party certification, arbitration-jurisdiction opinion or enforceability conclusion is supplied.
Research cutoff: October 8, 2026. Specific historical editions and events are identified in the rows.
| Object or field | Completed identity | Coordinate or version to preserve | Do not infer |
|---|---|---|---|
| Vienna treaty text | Vienna Convention on the Law of Treaties, 1155 U.N.T.S. 331 | Treaty-series volume 1155 and beginning page 331 | The volume/page pair alone does not establish a particular state's party status. |
| Vienna convention's signature-opening date | May 23, 1969 | The depositary describes adoption on May 22 and opening for signature on May 23 | Do not combine those different events into one unlabeled adoption date. |
| Vienna convention's general entry into force | January 27, 1980 | The date stated in the treaty's depositary record | General entry into force is not automatically the entry-into-force date for every later party. |
| Vienna registration identifier | Registration No. 18232 | A registration number separate from 1155 U.N.T.S. 331 | 18232 is not the UNTS volume or a treaty article. |
| New York treaty text | Convention on the Recognition and Enforcement of Foreign Arbitral Awards, 330 U.N.T.S. 3 | Treaty-series volume 330 and beginning page 3 | The popular name New York Convention does not identify a domestic New York statute. |
| New York convention's date and general entry into force | June 10, 1958; entry into force June 7, 1959 | Two labeled historical events | Do not cite 1959 as though it were the treaty's signature-opening year. |
| New York registration identifier | Registration No. 4739 | Registration identity distinct from series volume/page | A registration number does not replace the title in a reader-facing source identification. |
| Depositary participant entries | Signature, ratification, accession or succession fields | The selected state, relevant action, date and any associated declarations/reservations | A signature column must not be silently relabeled ratification. |
| UNCITRAL institution name | United Nations Commission on International Trade Law | Full institution name before defining UNCITRAL | The acronym alone does not identify a particular rule text or arbitral proceeding. |
| 2010 arbitration-rule publication | UNCITRAL Arbitration Rules, as revised in 2010 | The 2010 version label | A later publication link is not proof the later text governed a particular arbitration. |
| 2021 arbitration-rule publication | UNCITRAL Arbitration Rules with the 2021 expedited-rules addition | Preserve the version and the particular rules component | Do not treat the presence of expedited rules in the publication as consent to their use. |
| General Assembly document | A/RES/65/22 | Resolution identity associated with the 2010 revised Arbitration Rules | The resolution number is not an article number in the rules. |
| ICSID institution name | International Centre for Settlement of Investment Disputes | Full name before defining ICSID | Do not expand Centre to a different institutional name. |
| ICSID procedural publication | ICSID Arbitration Rules, 2022 version | Rule-set title and version, distinct from Institution Rules and the Convention | A shared ICSID cover does not make every component the same instrument. |

UN Treaty Collection status pages are time-stamped and include information beyond treaty text. Capture the relevant status record when the proposition concerns a state's action or reservation.
Some institution pages returned substantive official indexed text while direct page requests were blocked. The source register records that access limit. This table uses the supported publication metadata and does not claim to have inspected every underlying rule PDF or treaty article.
Primary sources and their scope: UN Treaty Collection: Vienna Convention on the Law of Treaties; UN Treaty Collection: Convention on Recognition and Enforcement of Foreign Arbitral Awards; UNCITRAL Arbitration Rules publication page; UNCITRAL General Assembly resolution list; ICSID Convention, Regulations and Rules; ICSID Rules and Regulations publication library; ICJ Judgment of 3 February 2012 in Jurisdictional Immunities of the State.
The UNCITRAL, ICSID and ICJ entries use substantive indexed text from the linked official pages; direct retrieval of those pages was unavailable or returned 403. These rows identify institutions, editions and publication metadata. They do not summarize the full rules, treaty obligations, party status or the judgment's holding.
