Style Guide for Chicago Manual Footnotes
About Chicago Manual Footnotes:
Footnotes are a conventional way to tell your readers where you got the information and quotes that appear in your paper. Your goal is to make it easy for your readers to see what sources you used -- and easy to find any that they might want to study further. To do that, you need to provide complete citations in a consistent citation style. Leading publishers of historical scholarship (such as the American Historical Review and the Journal of American History) require Chicago Manual style footnotes.
Below you will find model footnotes that cite various types of sources. (Using the search function of your browser is an easy way to find the type of source you need.) The models illustrate the format for the first reference to a particular item. A second reference to the same item can be shortened -- as in model footnote 2 below.
For more on what footnotes are and how they work, see below. For more details on Chicago-style footnotes, see the Chicago Manual itself (available at the Duggan Library). You may also find helpful the online Chicago-Style Citation Quick Guide.
This document was developed to provide illustrations of the types of citations our students use most. It includes examples from a version of "History: Documenting Sources" by Diana Hacker that is no longer available online.
Books (print format)
Book, most basic citation
1. Mark E. Neely, Jr., The Fate of Liberty: Abraham Lincoln and Civil Liberties (New York: Oxford University Press, 1991), 204.
For any book, follow this basic model for punctuation, capitalization, and italics -- providing author, title, place of publication, publisher, date of publication, and the page where the information you are citing can be found. Variations on this basic cite are modeled below. Note that a complete citation is needed for the first reference you make to any item; a shortened cite (as with model footnote 2) can be used thereafter.
Use this model for books available online only if they appear exactly as they did in print (i.e. with page images). Remember that the purpose of a footnote is to make it easy for readers to find the item you used. If the paper source and the online source look exactly the same (as would be the case in a photocopy, for instance), the details above will be most helpful for your readers. If the book has been reformatted in any way, your readers will need the URL and other information according to the model below.
Book, shortened citation
2. Neely, Fate of Liberty, 21.
Use this shortened style on second and subsequent cites to a particular item.
Book, with two or three authors
3. Michael D. Coe and Mark Van Stone, Reading the Maya Glyphs (London: Thames & Hudson, 2002), 129-30.
Book, with four or more authors
4. Lynn Hunt et al., The Making of the West: Peoples and Cultures (Boston: Bedford, 2001), 541.

Book, edited without an author
6. Jack Beatty, ed., Colossus: How the Corporation Changed America (New York: Broadway Books, 2001), 127.
Book, edited with an author

10. Jane Addams, Twenty Years at Hull House (1910; reprint, New York: Signet Classics, 2010), 44.
Use model footnote 9 for a book for which there are multiple revised editions. Use model footnote 9 when your readers need to know the original publication date as well as the specific reprint that you used.
Book, from a multi-volume work
11. James M. McPherson, Ordeal by Fire, vol. 2, The Civil War (New York: McGraw-Hill, 1993), 205.
12. Peter N. Stearns, ed., Encyclopedia of European Social History: From 1350 to 2000 (New York: Charles Scribner's Sons, 2001), III: 271.
For a separately titled volume, see model footnote 11; for volumes without individual titles (as with model footnote 12), provide the volume number with the pagination. Note that the cite to III:271 means page 271 of the third volume of the multi-volume set.
13. U.S. Department of State, Foreign Relations of the United States: Diplomatic Papers, 1943 (Washington, DC: GPO, 1965), 562.
Encyclopedias and other reference books
14. American Heritage Dictionary, New College Edition, s.v. "copy-edit ."
15. Encyclopaedia Britannica, 15th ed., s.v. "Monroe Doctrine."
Print encyclopedias and other reference books usually follow the models already provided for citing books -- see models for edited works, or multi-volume works above. The rare exceptions are dictionaries and a few widely recognized reference sources (such as the Encyclopedia Britannica), which are cited as above. (Note that "s.v." is for the Latin sub verbo, "under the word").
Use those models for reference works available online only if they appear exactly as they did in print (i.e. with page images). Remember that your goal is to make it easy for readers to find the item you used. If the paper source and the online source look exactly the same (as would be the case in a photocopy, for instance), the details above will be most helpful for your readers. If the book has been reformatted in any way, your readers will need the URL and other information as provided in the models below.
16. Matt. 20:4-9 (Revised Standard Version).
17. Koran 19:17-21.
For the Bible (model footnote 16), provide the book, followed by chapter and verse (i.e. 16 refers to the Gospel of Matthew, chapter 20, verses 4-9). For the Koran, provide sura and verse (i.e. model footnote 17 refers to sura 19, verses 19-21).

Note that the citation specifies the census year and provides the geographic location where the person was counted (the town or township, the county, and the state). If you found the census page through a commercial site, direct your readers to the appropriate search term for the digital image by giving the person's name as the commercial site indexed it ("s.v." stands for the Latin sub verbo, or "under the word."). Finally, provide the name of the commercial site you used.
Indexes and databases within a commercial site
35. "Social Security Death Index," s.v. "Richard W. Nixon" (1920-1991), Ancestry.com.

38. "U.S., World War I Draft Registration Cards, 1917-1918," s.v. "Samuel Beverly McNair," digital image, Ancestry.com.
Commercial sites like Ancestry.com may contain within them separate indexes or databases. Cite information from them by providing the title of the index/database, as given by the commercial site. Then provide the search term that readers will need for finding the information you're citing. Do that by giving the person's name as the commercial site indexes it ("s.v." stands for the Latin sub verbo, or "under the word."). You may also need to supply birth and/or death dates to distinguish among people with the same name. Be sure to note If a digital image is provided. (Otherwise, the index or database provides only the information, without reproducing the source from which the information came.) Finally, provide the name of the commercial site you used.

If you wish to refer to a source that the source you are consulting quotes, provide as much information as is available about the quoted source, and also provide the relevant information for the item in which it appears.
More on what footnotes are and how they work.
Footnotes are a conventional way to tell your readers where you got the information and quotes that appear in your paper. Complete citations in a consistent citation style make it easier for your readers to scan through your citations and find what they want quickly.
If you are reading this page from the Hanover College campus, you can click here to see an example of a published article using Chicago Manual style footnotes. (If this link does not work for you, contact your library to see if your institution provides access to scholarly journals through some other means.)
Suppose the second paragraph of your paper mentions Horatio Nelson Taft visiting the White House, and suppose one of your readers is curious about where she could read more about Taft. She will look for the next superscript number after your mention of Taft. (For most papers, there is a footnote at the end of each paragraph of text in the body of the paper, so she'll look first at the end of the paragraph.) The superscript number she finds in the text directs her to the appropriate spot on the numbered list that runs along the bottom of all your pages. There, your citation tells her that you learned about Taft's visit by reading his diary, and you give her all the information she needs to find a copy of the diary to read herself. (Standard citation styles give her enough information to find it online or to order it through interlibrary loan, for instance). If you quote Taft again later in your paper, she'll want to know more about that information too, and so she'll again look to the end of the paragraph for the superscript number that will direct her to the bottom of your page. There she'll find your shortened reference to the Taft diary, with the page where she can read the quote in context. If she has forgotten the diary's publication details, she can look back to your first footnote for all the specifics. If you follow a consistent citation style, she'll be able to find the first full cite easily by scanning up through your earlier footnotes.
Notice that footnotes are numbered consecutively over the course of the whole paper. (That is, the paragraph that mentions Taft the second time gets its own footnote; don't re-use the number found in the earlier paragraph.)
If you are confused about how to punctuate sentences with quotations and footnotes, remember that "the end punctuation goes first, followed by quotation marks as appropriate, and then the superscript number."1
If you are confused about how to find the details you need for a complete cite, you will find helpful visuals by following the "citation at a glance" links in Chicago Documentation Style at hackerhandbooks.com.
Scholarly journal house styles sometimes vary slightly from The Chicago Manual. For example, see the "Journal of American History Style Sheet".
Be careful to avoid accidental plagiarism. If you do not provide a footnote for information that you have learned from someone else, you are implying that you know that information from your own experience. You are thus stealing the credit for someone else's hard work, and academics take theft of intellectual property seriously.
