55. Secondary Publications: Edition, Component, and Update Decisions

55.1 Identify the work you actually consulted

Secondary publications often present a convenient discussion of several primary sources. Their value does not eliminate the need to identify the particular edition, article, chapter, release, or electronic version used. Citation Code's house record separates a work from its manifestation and its component. The work is the continuing title; the manifestation is the particular edition or release; the component is the chapter, article, section, comment, illustration, or note supporting the proposition.

This distinction lets a source system preserve both continuity and change. Two editions may share a title and author while using different section numbers. A contributed chapter may have an author different from the volume's editor. A model text may contain operative language, commentary, and illustrations that require different attribution. A source citation should preserve the differences relevant to the claim rather than collapsing all objects into “book, page.”

All publications and authors in this chapter's packets are fictional and bear TRAIN labels. The completed references are Citation Code house constructions for the supplied objects. They are not bibliographic assertions about actual books, journals, publishers, model-law organizations, or legal propositions. A real publication should use verified title-page, issue, revision, and component information, adjusted to the receiving instructions.

55.2 Packet P1: A new edition renumbers the discussion

Supplied packet. Dana Ellis's TRAIN Handbook of Record Analysis, second edition, published in 2022, discusses source reconciliation in § 4.2 at page 88. The third edition, published in 2026, moves the discussion to § 5.1 at page 114 and adds a qualification about incomplete exports. The writer read the second edition but a citation manager automatically replaced its year and edition with current catalog metadata while retaining page 88.

Completed reference for the inspected text: “Dana Ellis, TRAIN Handbook of Record Analysis § 4.2, at 88 (2d ed. 2022).” If the writer then reads and uses the third edition, the updated reference is “Dana Ellis, TRAIN Handbook of Record Analysis § 5.1, at 114 (3d ed. 2026).” The prose must also account for the added qualification when it matters. A catalog update is not evidence that the same proposition occupies the same page in a later edition.

For a historical comparison, cite both editions and state the change directly. For repeated use within one edition, a short reference can retain the section and pinpoint after the full identification. If both editions remain active in the document, retain “2d ed.” or “3d ed.” in the short references. The minimum useful short form depends on the set of competing sources, not just the number of words that can be removed.

55.3 Packet P2: Chapter author and volume editor

Supplied packet. TRAIN Essays on Legal Information, edited by Priya Moss, was published in 2025. Chapter 6, “Tracing Document Versions,” is by Eli Noor and begins at page 121. The relevant discussion is at pages 130–131. Moss wrote the volume introduction but not chapter 6. The draft cites “Moss, Essays, at 130,” and attributes the chapter's argument to the editor. The introduction begins on printed page vii; the passage in the variant is on printed page x.

Completed construction: “Eli Noor, Tracing Document Versions, in TRAIN Essays on Legal Information 121, 130–131 (Priya Moss ed., 2025).” This house form identifies the component author first, then the component title and host volume. The opening page locates the chapter; the later page range locates the relevant discussion. If the receiving style does not require the chapter's opening page, the source record should still retain it.

Variant — editor's introduction. A quotation from Moss's introduction at page x belongs to “Priya Moss, Introduction, in TRAIN Essays on Legal Information vii, x (Priya Moss ed., 2025).” Keep the printed Roman-numeral locator. Converting x into Arabic page 10 would redirect a reader to a different page sequence. The shared volume does not justify attributing both components to the same author or using a single undifferentiated page scheme.

55.4 Packet P3: Journal pagination and article numbers

Supplied packet. Lina Reed's “Document Drift” appears in TRAIN Journal of Legal Methods, volume 8, issue 2, beginning at printed page 201. The relevant passage is at page 219. The PDF viewer calls that PDF page 19 because the article's first page is 201. The article's identifier is TRAIN-ARTICLE-31. A second journal, TRAIN Digital Methods, uses article number e17 rather than continuous issue pagination; its PDF has local pages 1–14 and the relevant passage at local page 6. The first article was published in 2026. The second article is Lina Reed’s Reconstructing Source Sets, published in volume 3 of TRAIN Digital Methods in 2026.

Completed continuously paginated form: “Lina Reed, Document Drift, 8 TRAIN Journal of Legal Methods 201, 219 (2026).” The article identifier can be retained as an additional retrieval route when useful. Do not replace the printed pinpoint with the viewer count without labeling that coordinate and checking the receiving requirements.

Completed article-number form: “Lina Reed, Reconstructing Source Sets, 3 TRAIN Digital Methods, article e17, at 6 (2026).” The article number identifies the work within the journal; page 6 identifies the passage within the supplied PDF. The two numbers do different jobs. Do not present e17 as a conventional opening page or invent a continuous page range. If the article has assigned paragraph numbers, preserve those as another verified locator rather than generating numbers from extracted text.

55.5 Packet P4: Preprint and final article

Supplied packet. Omar Hale posts TRAIN Auditing Citation Systems, preprint version 1, on January 12, 2026. Section 3 at pages 9–10 describes a pilot of twelve tasks. Version 2, posted March 4, corrects the task count to ten. The final journal article, published July 2, reorganizes the discussion into section 4 at printed pages 44–45. The draft cites the final journal metadata while quoting a sentence removed after version 1.

Completed construction for the historical quotation: “Omar Hale, TRAIN Auditing Citation Systems 9 (preprint v1, Jan. 12, 2026).” Explain that the quotation comes from the earlier version if that fact matters to the discussion. For the corrected final study description, read and cite the final article's section 4 and pages 44–45, using its supplied journal metadata. A stable title or author identifier does not make every version's wording identical.

The source record should connect v1 → v2 → final while keeping each file and its distinct locators. A later publication is not automatically a warrant to cite an earlier quotation under newer metadata. If the final article's publisher page supplies a correction notice, treat that as another source object and inspect its effect. The citation system should permit a writer to discuss version history explicitly rather than overwriting it with a single latest-record field.

55.6 Packet P5: Looseleaf section and replacement release

Supplied packet. TRAIN Practice Service is maintained by replacement pages. Section 7.14 has release 18, dated October 2024, and release 22, dated February 2026. Both use the same section number. The release-18 page carries footer “7-42,” while release 22 adds a paragraph and shifts the relevant discussion to “7-43.” The library binder contains a mixture of updated and older sections, with the insertion checklist showing only which pages were replaced.

Completed construction: “TRAIN Practice Service § 7.14, at 7-43 (release 22, Feb. 2026).” Retain the section's actual release data rather than assigning the binder's original publication year to every page. If a historical quotation comes from release 18, cite that release and page 7-42. The current binder's appearance does not establish what an earlier release said.

Variant — online counterpart. An online version displays “§ 7.14, updated March 10, 2026,” with numbered paragraphs but no page 7-43. If that is the version inspected, use the supplied update date and paragraph locator. Do not import the looseleaf page number unless the electronic text actually preserves and verifies it. Store the online and looseleaf manifestations separately so a citation exporter cannot assemble a hybrid that exists in neither source.

55.7 Packet P6: Model text, comment, and enacted variant

Supplied packet. The fictional Training Drafting Council issues TRAIN Model Records Act, final approved text dated May 2025. Section 6(a) contains proposed statutory language. Comment 2 explains an example, and Illustration 3 supplies fictional facts. A separate Training Assembly enactment, TRAIN-ACT-P6, adopts part of § 6 with changed wording. The draft quotes Comment 2 while citing only “Model Act § 6” and calls it enacted law.

Completed component reference: “Training Drafting Council, TRAIN Model Records Act § 6 cmt. 2 (final approved text, May 2025).” For the illustration use “§ 6 illus. 3.” For the model's proposed statutory words use “§ 6(a).” For the actual words of the fictional adopting act, cite TRAIN-ACT-P6 and compare its text. These references identify different authorial and legal objects even when they appear together in a research packet.

A tentative draft of the model text would require its draft number and date. Do not remove “tentative” because a later final publication uses the same title. Likewise, a commentary passage is not transformed into enacted text merely because the legislature adopted a related section. The citation construction should preserve the difference before the writer analyzes what interpretive significance, if any, the comment has under applicable law.

55.8 Prevent publication metadata from silently rewriting the source

Treat imported catalog data as a proposed match. Compare author, title, edition, component, publication year, and identifiers against the inspected object. A citation manager can help format known fields, but it should not replace a verified second-edition record with a third-edition record merely because the title matches. Preserve the old record when both editions are used. The source file and the rendered bibliography should point to the same manifestation.

When a secondary source cites a primary source, keep the two inspection states separate. If the primary text has not been read, do not present the secondary source's quotation as an independently verified primary-source quotation. Attribute the report accurately and identify the follow-up needed. If the primary text is later obtained, compare the passage and update the support rather than simply swapping the citation label. A complete secondary reference can make the research chain visible while the primary-source check remains pending.
