Chicago 17 Citation Guide for History Students
History writing depends on precise source documentation more than almost any other discipline. The Chicago Manual of Style, 17th Edition (Notes-Bibliography system) is the standard citation format across historical scholarship—from undergraduate research papers to peer-reviewed journal articles. This guide addresses the specific challenges history students face: citing primary sources, navigating archival collections, formatting government documents, and handling the unpublished materials that make historical research distinctive. Every example below shows the full citation lifecycle: first footnote, shortened footnote, and bibliography entry.
Why Chicago Notes-Bibliography for History?
History departments almost universally require the Notes-Bibliography (NB) system rather than the Author-Date system used in the social sciences. The reason is structural: historical arguments build through layered engagement with sources in footnotes and endnotes, where discursive commentary often accompanies citations. The NB system supports this by allowing substantive notes alongside bibliographic references—something parenthetical systems like APA 7 or MLA 9 cannot accommodate as naturally.
The NB system uses two components: notes (footnotes or endnotes, numbered sequentially throughout the paper) and a bibliography (an alphabetical list of all sources at the end). The first note for any source gives full publication details. Subsequent references use a shortened form. The bibliography inverts the first author's name for alphabetical sorting.
Core Formatting Rules to Internalize
- Notes use normal name order (First Last), commas between elements, and parentheses around publication details for books.
- Bibliography entries invert the first author's name (Last, First), use periods between major elements, and omit parentheses around publication details.
- Shortened notes include only the author's last name, a shortened title, and page number.
- Ibid. may be used for consecutive references to the same source, but many history departments now discourage it in favor of shortened notes. Check your department's style sheet.
- Page numbers are required in notes when citing specific passages. Bibliography entries for books omit page numbers; entries for journal articles include the full page range.
Books: The Foundation of Historical Citation
Monographs remain the primary vehicle for historical scholarship. Getting book citations right is essential before tackling more complex source types.
Single-Author Monograph
First footnote:
Shortened footnote:
Bibliography:
Note the critical differences: the footnote places publication information in parentheses and ends with a page number. The bibliography inverts the author's name, replaces commas with periods between major elements, removes the parentheses, and drops the specific page number.
Two or Three Authors
First footnote:
Shortened footnote:
Bibliography:
Only the first author's name is inverted in the bibliography. The second (and third) author keeps normal order. For four or more authors, the footnote lists all authors on first reference or uses the first author followed by "et al." The bibliography lists all authors up to ten; for eleven or more, list the first seven followed by "et al."
Edited Volume with a Chapter by a Specific Author
History anthologies and essay collections are common. When citing a specific chapter or essay, the chapter author is the primary reference point.
First footnote:
Shortened footnote:
Bibliography:
When a chapter appears in a volume edited by someone other than the chapter author, add the editor after the book title:
First footnote:
Bibliography:
Note that "ed." in notes becomes "edited by" in the bibliography.
Translated Works
Working with translated sources is routine in history. The translator appears after the title.
First footnote:
Shortened footnote:
Bibliography:
Reprints and New Editions
History students frequently cite reprints of older works. Include the original publication date when it is historically significant.

Journal Articles
Historical journal articles follow a consistent pattern. Pay close attention to the distinction between page numbers in notes (specific pages cited) and in the bibliography (full page range of the article).
Standard Journal Article
First footnote:
Shortened footnote:
Bibliography:
The pattern is: volume number, comma, "no." followed by issue number, season or month and year in parentheses, colon, page(s). The bibliography gives the full page range (1347–76) while the note gives only the specific page referenced (1349).
Journal Article Accessed Online with DOI
First footnote:
Bibliography:
When a DOI is available, always include it. It is more stable than a URL. Chicago 17 formats DOIs as full URLs beginning with https://doi.org/.
Book Review in a Journal
Book reviews are a staple of historical literature. They have a specific format.
First footnote:
Bibliography:
Primary Sources: The Heart of Historical Research
Primary source citation is where history diverges most sharply from other disciplines. Most citation guides cover secondary sources adequately but leave students struggling with manuscripts, letters, diaries, and other unpublished materials. This section addresses the source types you will actually encounter in archives.
Unpublished Manuscripts and Archival Documents
Archival citations must allow a future researcher to locate the exact document. The key elements are: the specific document, the collection or record group, the box and folder numbers (if applicable), the repository name, and its location. Chicago 17 does not prescribe a single rigid format for archival materials—clarity and consistency are the governing principles.
First footnote:
Shortened footnote:
Bibliography:
For larger archival collections cited repeatedly, establish an abbreviation in your first note and use it throughout:
First footnote (establishing abbreviation):
Subsequent footnote:
Bibliography:
In the bibliography, archival collections are typically listed by collection name rather than individual document. If you cite only one or two documents from a collection, you may list them individually.
Personal Letters, Diaries, and Memoirs (Unpublished)
First footnote:
Shortened footnote:
Bibliography:
Published Collections of Primary Sources
Many primary sources are available in edited collections. Cite these like edited books, with the specific document identified in the note.
First footnote:
Shortened footnote:

Common Mistakes with Archival Citations
Wrong: Providing vague repository information that would prevent another researcher from locating the document.
Correct: Include the author, recipient, date, collection name, box/folder, repository, and city.
Wrong: Citing individual archival documents in the bibliography when you use many items from the same collection.
Correct: List the collection as a whole in the bibliography. Individual documents are identified in the notes.
Government Documents
Government documents are essential to political, legal, diplomatic, and social history. They follow special citation patterns because they often lack named individual authors.
Congressional Records and Debates
First footnote:
Shortened footnote:
Bibliography:
The Congressional Record is typically cited only in notes. If included in the bibliography, cite the volume as a whole.
Congressional Hearings and Reports
First footnote:
Shortened footnote:
Bibliography:
Presidential Documents
First footnote (executive order):
Shortened footnote:
Bibliography:
Published Government Reports
First footnote:
Shortened footnote:
Bibliography:
Supreme Court Decisions
Legal citations in history papers can follow either standard legal citation (Bluebook) or Chicago format. For history papers, Chicago style is generally acceptable unless your department specifies otherwise.
First footnote:
Shortened footnote:
Bibliography:
Court cases are typically cited only in notes. Include them in the bibliography only if they are central to your argument.

Historical Newspapers
Newspapers are vital primary sources for social, cultural, and political history. Chicago 17 has specific rules for newspaper citations that differ from journal articles.
Named Article with Byline
First footnote:
Shortened footnote:
Bibliography:
Unsigned Newspaper Article
Many historical newspaper articles lack bylines. Cite them by article title or, if untitled, by a descriptive phrase.
First footnote:
Shortened footnote:
Bibliography:
Important: Chicago 17 notes that newspapers cited in notes need not appear in the bibliography at all. If you do include them, you may list the newspaper as a whole ("Articles from the New York Times are cited in the notes") or list individual articles. Whichever approach you choose, apply it consistently.
Historical Newspapers from Digital Databases
First footnote:
Shortened footnote:
Bibliography:
Include the database name when the newspaper was accessed through a digital archive. You do not need to include a URL for well-known databases, but if your instructor requires it, add the stable URL or document ID at the end.
Digital and Online Sources
Historians increasingly work with digitized primary sources and born-digital materials. Chicago 17 provides clear guidance for these.
Website or Blog Post
First footnote:
Shortened footnote:
Bibliography:
Digitized Primary Source from an Institutional Repository
First footnote:
Shortened footnote:
Bibliography:
When a primary source is accessed in a digitized form, cite the original document details first, then add the digital repository information. This ensures the citation works whether or not the digital version remains available.
E-book Editions
First footnote:
Shortened footnote:
Bibliography:
For e-books without fixed page numbers, cite chapter numbers or section headings instead. If the e-book has stable page numbers matching the print edition, cite those pages normally and omit the format note.
Theses, Dissertations, and Conference Papers
Unpublished academic works are common sources in historiography, especially for cutting-edge research not yet in print.
Unpublished Dissertation
First footnote:
Shortened footnote:
Bibliography:
Dissertation and thesis titles are enclosed in quotation marks (not italicized) because they are unpublished works.
Conference Paper
First footnote:
Shortened footnote:
Bibliography:
Maps, Images, and Non-Textual Sources
Visual and material sources require careful citation that identifies both the object and its location or publication context.
Historical Map

Common Formatting Errors in History Papers
These are the mistakes history instructors see most frequently. Avoid them.
Error 1: Using parenthetical citations instead of footnotes.
This is Author-Date style, not Notes-Bibliography. History papers require numbered footnotes or endnotes.
Correct:
Error 2: Using bibliography formatting in footnotes.
Notes use commas, normal name order, and parentheses around publication details. This note incorrectly uses periods, inverted name, and no parentheses—that is bibliography format.
Correct:
Error 3: Omitting page numbers in notes.
Shortened notes must include a page number when referencing a specific passage.
Correct:
Error 4: Italicizing article or chapter titles.
Only titles of larger works (books, journals, newspapers) are italicized. Articles, chapters, and other shorter works use quotation marks.
Correct:
Error 5: Using "p." or "pp." before page numbers.
Chicago style does not use "p." or "pp." with page numbers in notes or bibliography entries.
Correct:

Frequently Asked Questions
Should I use footnotes or endnotes for my history paper?
Chicago 17 permits both, and the choice is often dictated by your instructor or department. Footnotes appear at the bottom of the page where the citation occurs, making them immediately accessible to readers—most history faculty prefer this. Endnotes collect all notes at the end of the paper or chapter, producing cleaner page layouts but requiring readers to flip back and forth. For seminar papers and journal articles, footnotes are standard. For dissertations and books, endnotes are increasingly common for production reasons. When in doubt, ask your instructor. Whichever you choose, the formatting of the notes themselves is identical.
How do I cite a source I found quoted in another source (secondary citation)?
History instructors strongly prefer that you consult original sources whenever possible. However, when the original is unavailable—destroyed, untranslated, or held in an inaccessible archive—you may cite it as "quoted in" the secondary source.
Footnote:
The bibliography entry is for the secondary source (Larson's book), since that is the work you actually consulted. Use "quoted in" sparingly—over-reliance on secondary citations signals insufficient archival engagement.
Do I need a separate bibliography section for primary sources?
For substantial research papers, dissertations, and theses, dividing the bibliography into sections is standard practice and highly recommended. The most common division is:
- Primary Sources (further subdivided into "Archival Collections," "Published Primary Sources," and "Newspapers" if the list is long)
- Secondary Sources
For shorter seminar papers, a single alphabetical bibliography is usually sufficient. Follow your department's guidelines or ask your instructor.
How do I handle sources in languages other than English?
Cite foreign-language sources in their original language. Capitalize titles according to the conventions of that language (e.g., French and Spanish capitalize only the first word and proper nouns in titles, unlike English). If you provide a translation of the title, place it in brackets after the original title. Do not italicize the translated title.
First footnote:
Bibliography:
When should I use "accessed" dates for online sources?
Chicago 17 recommends access dates for online sources that lack a publication or revision date, or for content that may change over time (such as websites and databases). For formally published online journal articles with DOIs, an access date is not necessary. For digitized archival materials, government websites, and other potentially ephemeral sources, include the access date. Format it as: "Accessed March 5, 2026."
How do I cite the same source many times without cluttering my notes?
Use shortened notes consistently after the first full citation. If your paper relies heavily on a single source for an extended passage, you may state in a note that "all quotations in the following three paragraphs are from" the source and its page range. This avoids repetitive notes while maintaining transparency. For archival collections, establish abbreviations on first reference and use them throughout. Some historians also use a "List of Abbreviations" at the beginning of the paper for works cited frequently.
Quick Reference: Note vs. Bibliography Formatting
This table summarizes the key structural differences between notes and bibliography entries for the most common source types in history papers.
| Element | In Notes | In Bibliography |
|---|---|---|
| Author name | First Last | Last, First |
| Separators | Commas | Periods |
| Book pub. info | (Place: Publisher, Year) | Place: Publisher, Year. |
| "ed." / "trans." | Abbreviated: ed., trans. | Spelled out: edited by, translated by |
| Page numbers (books) | Specific page(s) cited | Omitted |
| Page numbers (articles) | Specific page cited | Full page range |
| Article/chapter titles | "In quotation marks" | "In quotation marks" |
| Book/journal titles | Italicized | Italicized |
Comparing Citation Styles for History
While Chicago NB is dominant in history, you may encounter other styles in interdisciplinary work. APA 7th Edition is common in social science approaches to history (quantitative history, historical psychology), while MLA 9th Edition appears in literary and cultural history contexts. The key advantage of Chicago for history is its footnote system, which supports the kind of discursive, source-layered argumentation that defines the discipline. If your course or journal specifies a different style, follow that—but for standard history departments, Chicago NB is the expected format.
