Fictional training example — not legal authority.

Harbor Notice Bill, H.R. 9000, 119th Cong. § 3(b) (2025). The supplied chamber/number, Congress, section, and year distinguish this invented bill. Additional introduced-version language can improve clarity if competing versions are being discussed. The training metadata does not identify real legislation, and the title is not evidence that any measure became law.

A bill's number belongs to a particular Congress and chamber, so those fields identify the proposal before its section is added. The packet supplies the introduced stage but not a complete introduction date. Preserve that status where the discussion requires it without inventing a day. The section and year describe this fictional source rather than an enacted public law.

Do not turn H.R. 9000 into Pub. L. No. 119-9000. A bill number does not establish enactment or supply the separate numbering of an enacted law.

Check chamber/type, number, Congress, section, year, and introduced status against the packet. Keep the fictional label with the citation.

H.R. Rep. No. 119-500, at 12 (2025). The report number includes the supplied Congress and report sequence, while at 12 locates the committee explanation. Attribute that explanation to the report rather than enacted statutory text. Every report field in the packet is fictional. A real report requires an inspected official item and its actual passage.

A committee report has a publication number independent of the bill it discusses. Its number identifies the report, and the at-page locator selects the explanation on page 12. The prose should attribute a report's explanation to that source. A sentence about enacted duties would need the actual enacted language and any other necessary interpretive authority.

Do not substitute H.R. 119-500 as though the report were a bill. Removing Rep. changes the source type, not merely its length.

Open the report's page 12 and ask whether your sentence describes the committee explanation or incorrectly announces a statutory command.

Identify the introduced version and its actual date or other version designation from the supplied document. Read that version's section 3 rather than the passed version's different text. Preserve the version in the source card and citation where needed to distinguish it. Do not silently quote one stage while identifying another or invent a date missing from the packet.

Legislative text can change between introduction and passage. A quotation is tied to the version containing those words, even when its bill number remains constant. The source card must preserve the actual version identifier and the passage inspected. If the packet lacks a precise date, identify the stage that is supplied and record the missing field honestly.

Do not label introduced language as the passed version because that version is easier to retrieve. Matching bill numbers do not prove matching section text.

Compare the quoted words and version label together. Both must come from the same identified stage of the bill.

A witness speaks in the witness's own capacity and can advocate, predict, or describe facts. The statement is not automatically a committee position or an enacted legislative command. Attribute it to the speaker and hearing, using the actual page. To state what law commands, inspect the enacted provision and applicable interpretive authority. Citation format cannot merge those source roles.

A hearing gathers statements from speakers with distinct roles. A witness's testimony may inform legislative deliberation without becoming the committee's conclusion or the enacted law. The citation's speaker information and pinpoint should preserve that distinction. If the sentence needs a legislative command, changing the speaker's name or adding a hearing citation cannot supply the missing enactment.

Do not write Congress determined merely because a witness testified before Congress. The institutional setting does not transfer authorship of the statement.

Identify the actual speaker beside the passage, then use a sentence verb that describes that speaker's statement rather than legislative enactment.

A bill number identifies a proposal within a legislative body/session; a public-law number identifies an enacted law by Congress and sequential enactment number. The inspected historical citation is Pub. L. No. 89-487, 80 Stat. 250, 251 (1966). Page 250 identifies the enactment's beginning, and page 251 contains its original effective-date provision. The approval line dates enactment July 4, 1966; the original provision specifies effectiveness one year following enactment. A claim about a later operative period would require the applicable later statute and amendments, not an assumption that the original enactment alone supplies current law.

The exercise concerns the original law and its effective-date clause, so a historical session-law citation is appropriate. The public-law number identifies the enactment; the first Statutes at Large page identifies its beginning; the pinpoint identifies the clause being described. Keeping the approval line and later effective timing separate avoids turning a publication fact into an applicability conclusion.

Do not use the bill's earlier identifier as though it were the enacted citation, or say the original provision operated immediately when its text specifies a later time.

Find page 251's timing provision and the approval line, then explain their relationship without assuming anything about later amendments.

The I.R.C. corresponds to title 26 of the United States Code. Treasury regulations are administrative regulatory text issued under statutory authority and use their specialized Treas. Reg. identification pattern. They are different instruments even when organized around related statutory sections. The exercise teaches classification; it does not independently verify a tax obligation or source's present reliance status.

A tax statute and a Treasury regulation can address related subject matter while remaining different forms of authority. Source classification must precede selection of the abbreviation and locator. Title 26 identifies statutory organization; a Treasury-regulation designation identifies an administrative instrument. Their related numbering does not mean that text in one necessarily appears in the other.

Do not attach Treas. Reg. to a statutory section simply because tax research is involved. First identify the actual document whose words support the sentence.

Read the source's own title and instrument label. Can you explain whether Congress's statutory text or an administrative regulation is being cited?

Determine whether the item is a revenue ruling, private letter ruling, revenue procedure, Treasury decision, or another instrument. Recover its complete number, date, issuing body, bulletin/publication locator or access source, actual text, and status as applicable. A bare Ruling 123 cannot supply a full citation or legal-force conclusion. Record any missing information instead of fabricating it.

Specialized instruments use identifying schemes that convey source type as well as sequence. The fragment Ruling 123 lacks enough information to choose a format or assess the statement's role. Recover the complete official item before constructing its citation. If the fragment came from another author, follow that lead to the source instead of treating the fragment as verified metadata.

Do not guess that Ruling means revenue ruling. A private letter ruling or another instrument would require different identification and may raise different reliance questions.

Can you open one uniquely identified item and locate the relevant passage? If not, stop the citation at an unresolved-source record.

An uncodified provision may appear in the enacted session law without a current code location. The session-law citation then identifies the actual text needed. An amendment's enacted wording or historical enactment can also require that source. Inspect the item and precise section/page rather than assuming every legal command was incorporated into the organized code.

Codification is an organizational process; the absence of a current code section does not erase an enacted provision. Session-law sources can preserve transition language, effective dates, and uncodified provisions needed for a specific proposition. The correct citation should identify the actual enactment and its passage rather than force the material into an unrelated code section.

Do not use the nearest codified section merely because it concerns the same topic. Topical proximity is not proof that the section contains the uncodified command.

Trace the sentence to a particular public-law or session-law provision and page. Verify that the cited text actually contains the claimed instruction.

Locate an official version history or another authorized record identifying the saved text's stage/date, then compare its relevant passage with the revised version. Record what was actually found and whether the earlier source can be identified. If it cannot, mark the version unresolved and avoid an unsupported historical quotation. Do not reconstruct imagined legislative steps to make the notes appear complete.

A saved excerpt without version information is evidence of words but may be insufficient evidence of their legislative stage. Search official version records using distinctive language and known identifiers, then compare the relevant section. Document both a successful match and any remaining uncertainty. A revised online page cannot retroactively identify an unmarked earlier excerpt without that comparison.

Do not infer that the saved excerpt was introduced text merely because the live item is later. Other stages or revisions may exist, and no chronology was supplied.

Can another reader reproduce your version match from an official record? If not, qualify or remove the historical claim instead of inventing its provenance.
