This chapter shows you how to use the Chicago notes-bibliography style. In Chicago style, you use numbered notes for the citations in your text. Whenever you use the words or ideas of a source, you mark the place in your text with a raised number called a superscript and give the information about the source in a correspondingly numbered note. You then collect all of the sources you have cited into an alphabetical listing called a bibliography. This list should also include any works that you did not cite but that influenced your thinking. In special cases, you may include all sources you consulted, even if you did not use them in any way; but ask your teacher before you do so.

The forms for notes and bibliography entries are different for different kinds of sources, but for each kind of source a note and bibliography entry are similar:

Note for Journal Article

1. Tim Hitchcock, “Begging on the Streets of Eighteenth-Century London,” Journal of British Studies 44, no. 3 ( July 2005): 489.

Bibliography Entry for Journal Article

Hitchcock, Tim. “Begging on the Streets of Eighteenth-Century London.” Journal of British Studies 44, no. 3 ( July 2005): 478—498.

Note for Book

2. Philip Ball, Bright Earth: Art and the Invention of Color (New York: Farrar, Straus and Giroux, 2001), 99.

Bibliography Entry for Book

Ball, Philip. Bright Earth: Art and the Invention of Color. New York: Farrar, Straus and Giroux, 2001.

Although they look similar, these forms vary in small but important details such as order of elements, punctuation, capitalization, and abbreviations. So be sure you use the right kind of example and pay close attention to these details. To help you avoid confusing the note form with the bibliography-entry form, we have listed them in different sections (18.1 Notes and 18.2 Bibliography).

How to Use This Chapter

This chapter presents models for the most common kinds of sources. You will find models for notes in section 18.1 and for bibliography entries in 18.2. Within each section, the models are listed by kind of source: articles, reference works, websites and blogs, and books. Follow these steps:

1. Find a model.

✵ Find the model that matches your kind of source. For instance, if you need to cite a scholarly journal article in an online database, find the example for “Online Journal.”

✵ Be certain that your source is in the same category as the example. If your source does not match any of the examples in this book, do not guess. Consult a more comprehensive guide, such as Kate. L. Turabian, A Manual for Writers of Research Papers, Theses, and Dissertations, 7th ed. (Chicago: University of Chicago Press, 2007).

2. Match the model.

✵ Create your citation by exactly matching the bibliographical information on your source to each detail in the model, point for point. Make sure that your note or bibliography entry corresponds to the model in every detail, including capitalization, abbreviations, punctuation, and spacing.

✵ If your source has multiple authors, consult the information on authors' names in section 18.1.2.1 (notes) or 18.2.1.1 (bibliography).

3. Adjust, but only if necessary.

✵ You may make reasonable small adjustments if your source is the same kind as a model but its bibliographic information is slightly different. For example, if the person who put together a book of collected material is called a “compiler” rather than an editor, you may use the form for an edited volume and use the word “compiler” or the abbreviation “comp.” wherever the example uses “editor” or “ed”: 68. Henry Jones, compiler, The Oxford Book of . . .

Many of you will use software packages that format citations for you automatically. You may let your software create a first draft of your citations, but do not trust it to produce the correct form. If you use an automatic citation builder, recheck each note and bibliography entry. Find the appropriate example and match it to the citation point by point. It is easy to miss small but important details when a citation is already formatted for you, so go slowly and be careful.

18.1 Notes

18.1.1 When and How to Add Notes

You must indicate in your text every place where you use the words or ideas of a source. In most cases, you should cite a source in a numbered note, with a corresponding number inserted in your text. The exact form of the note depends on the kind of source you cite: journal article, website, book, and so on. For sources you cite often, you can use parenthetical references.

For a quotation or paraphrase, insert the note number or parenthetical reference at the end of the quotation or at the end of the sentence that includes it:

The founding fathers' commitment to religious freedom was based on their commitment to the freedom of ideas. They were adamant that the “coercion of the laws” cannot apply to “the operations of the mind” in the way that they must apply to “the acts of the body.”3

For ideas or methods, insert the note number at the end of the sentence in which you first introduce or explain the borrowed material. Be sure to cite every source that influenced your thinking, even if you do not quote or paraphrase from it. A reader might think you're guilty of plagiarism if you seem to reflect the ideas of a text that you do not cite. (See chapter 10.)

Notes are called footnotes if you put them at the bottom of the page or endnotes if they are in a separate list at the end. Most readers find footnotes easier to use because they can see the text and the note at the same time, without turning to the end of the paper. Ask your teacher what she prefers, but if you have a choice, use footnotes.

18.1.1.1 Numbered Notes

Most citations in your paper should be in numbered notes. Use your word-processing software to insert into your text a raised number, or superscript, that directs readers to a correspondingly numbered note.

Most Americans think of homelessness as a recent development, but it has always been part of the American heritage. Beggars had long been common in London,1 which led early Americans to think of homeless beggars as a normal feature of city life. Of course, America's early cities . . .

1. Tim Hitchcock, “Begging on the Streets of Eighteenth-Century London,” Journal of British Studies 44, no. 3 ( July 2005): 489.

The superscript in your text must be after any punctuation:

NOT: . . . London1, which . . . BUT: . . . London,1 which . . .

Your word-processing software should format the note for you. If not, do this:

✵ Number each note with a superscript. (It is acceptable if your software uses a number followed by a period: 1. Tim Hitchcock, “Begging . . .”).

✵ Indent each note like a paragraph.

✵ Single-space notes with a blank line between notes.

✵ For footnotes, put a line between the body text and the first footnote on each page.

✵ For endnotes, list all notes starting on a new page after the text but before the bibliography; center the heading “Notes” at the top.

18.1.1.2 Shortened Notes

If you refer to the same source more than once, you can use a short form after the first note. The first note must give the full citation. After that, give enough information to identify the source, usually the author's last name and a word or two from the title. If you add page numbers, put a comma after the title and then the pages (but do not use p. or pp.).

Most Americans think of homelessness as a recent development, but it has always been part of the American heritage. Beggars had long been common in London,1 which led early Americans to think of homeless beggars as a normal feature of city life. Of course, America's early cities did not have extensive slums, which were the source of most of London's beggars.2 Nevertheless . . .

1. Tim Hitchcock, “Begging on the Streets of Eighteenth-Century London,” Journal of British Studies 44, no. 3 ( July 2005): 489.

2. Hitchcock, “Begging,” 491.

18.1.1.3 Parenthetical References in the Text

Although most citations should be in notes, you can use parenthetical references if you have several citations to the same source. This is common when your paper analyzes one or two texts, as in many literary, philosophical, or historical essays.

In these cases, the first reference to the source should be a complete note:

3. Thomas Jefferson, Notes on the State of Virginia, ed. William Peden (New York:

W. W. Norton & Company, 1954), 16.

After that, you can use a short parenthetical reference inserted into your text each time you cite this source. Give just enough information to match the reference to the full citation given in the note. In most cases, you should include only the author's last name and page number, separated by a comma:

The founding fathers' commitment to religious freedom was based on their commitment to the freedom of ideas. They were adamant that the “coercion of the laws” cannot apply to “the operations of the mind” in the way that they must apply to “the acts of the body” ( Jefferson, 159).

If you mention the author's name in your text, you can give just the page number in parentheses:

. . . their commitment to the freedom of ideas. As Thomas Jefferson put it, the “coercion of the laws” cannot apply to “the operations of the mind” in the way that they must apply to “the acts of the body” (159).

If, however, your paper cites two works by the same author, you need to give both the author's name and a keyword or two from the title so that readers will know which work you are citing:

. . . the “coercion of the laws” cannot apply to “the operations of the mind” in the way that they must apply to “the acts of the body” ( Jefferson, Notes, 159).

18.1.2 Elements Common to All Notes

When you create a note, you have to pay attention to the kind of source you are citing, because many elements of notes are different for different kinds of sources. But almost all notes consist of four basic elements—author's name, title of the work, publication facts, and page numbers.

18.1.2.1 Author's Name

The first element in a note is always the name of the author or authors. You should give the full name of the author exactly as it is shown in the source: use initials only if that's how the name appears. Do not include titles such as Sir, Saint, Sister, Reverend, Doctor, and so on. List all authors' names in regular order: first—middle—last. (Note: Authors are listed differently in bibliography entries; see 18.2.1.1.)

Single Author

4. Michael Pollan, The Omnivore's Dilemma . . .

5. J. K. Rowling, Harry Potter and . . .

Multiple Authors

If there is more than one author, list them in the order shown in the source. For three or more authors, put a comma between names and add and before the last name.

6. Steven D. Levitt and Stephen J. Dubner, Freakonomics . . .

7. Joyce Heatherton, James Fitzgilroy, and Jackson Hsu, Meteors and Mudslides . . .

If there is no author listed in the source, begin the note with the title of the work.

18.1.2.2 Title

Give the title exactly as it is shown in the source, including a subtitle if there is one. For articles and other short works, you will need both the article title and the title of the book, journal, or other work in which it occurs. If an online source does not have an obvious title, use the name of the site or any other reasonable replacement.

Capitalize titles headline style: capitalize the first and last words of the title and subtitle and all other words except articles (a, an, the), coordinate conjunctions (and, but, or, nor, for, so, yet), prepositions (of, in, at, above, under, and so forth), and the words to and as. If a title includes a subtitle, put a colon between the main title and the subtitle. With few exceptions, titles are set off in quotations marks or italics.

QUOTATION MARKS: ARTICLES, CHAPTERS, WEB PAGES, AND OTHER SHORT WORKS. Put the titles of short works that are part of longer ones in regular type, enclosed in quotation marks.

8. Tim Hitchcock, “Begging on the Streets of Eighteenth-Century London,” . . .

9. Charlotte M. Porter, “Artist-Naturalists in Florida,” Florida Museum of Natural History (website), accessed May 1, 2009, http://www.flmnh.ufl.edu/naturalists/.

ITALICS: BOOKS, JOURNALS, MAGAZINES, NEWSPAPERS, AND BLOGS. Put the titles of longer works in italics. If the title includes a title, put it in quotation marks and italics.

10. Thomas Jefferson, Notes on the State of Virginia, . . .

11. Tim Hitchcock, “Begging on the Streets of Eighteenth-Century London,” Journal of British Studies . . .

12. John E. Sitter, The Poetry of Pope's “Dunciad,” . . .

18.1.2.3 Publication Facts

In addition to the author's name and title of the work, a note usually includes facts that identify where and when a source was published. Publication facts vary from one kind of source to another, so check each model carefully.

For online sources, you must also include the date you accessed the source and a complete online address or URL (uniform resource locator). In most cases, you should include the URL exactly as it appears in your browser bar, even if it is very long.

13. . . . Florida Museum of Natural History (website), accessed May 1, 2009, http://www.flmnh.ufl.edu/naturalists/.

Most word processors will not break URLs if they spill over a line, but you can force a line break after a slash (/). If that still leaves a mostly empty line, you can force a break before a period, equal sign, or other punctuation.

18.1.2.4 Page Numbers

If you cite a specific passage in a source, you must indicate where readers can find that passage, usually by adding a page number. The page number (or numbers) may be preceded by either a comma or a colon, depending on the type of source. Do not include the word page or the abbreviations p. or pp. before the number.

14. Tim Hitchcock, “Begging on the Streets of Eighteenth-Century London,” Journal of British Studies 44, no. 3 ( July 2005): 489.

If you cite a range of pages, include all the digits in both numbers: do not abbreviate the second (not 127—32).

15. Philip Ball, Bright Earth: Art and the Invention of Color (New York: Farrar, Straus and Giroux, 2001), 98—99.

If you cite material from a table or lines from a poem, use the word table or line(s) and an identifying number(s).

16. Kenneth T. Jackson, Crabgrass Frontier: The Suburbanization of the United States (New York: Oxford University Press, 1985), table 1.

17. Ogden Nash, “Song for Ditherers,” lines 1—4.

Many online sources do not have page numbers. If the source has a label for the section you quote, a heading, or a numbered paragraph, then use that as a locator. Otherwise, you can skip this element.

18.1.3 Notes for Periodical Articles

Most of the articles you will consult will be found in periodicals—journals, magazines, newspapers, and other works published at periodic intervals in print form, online, or both.

Journals are scholarly or professional periodicals written for experts and available primarily in academic libraries. Journals often include the word journal in their titles ( Journal of Modern History), but not always (Postmodern Culture).

Magazines are not scholarly publications; they are designed for more general readers in both their content and their availability outside of academic settings. If you are unsure whether a periodical is a journal or a magazine, see whether its articles include citations; if so, treat it as a journal.

Newspapers are generally daily or weekly publications whose articles are closely tied to recent events.

The Basic Pattern

Print Journal

If a journal lists both a volume and issue number, include both; list the date as it is printed on the journal (year, month + year, or season + year).

18. Ann Grodzins Gold, “Grains of Truth: Shifting Hierarchies of Food and Grace in Three Rajasthani Tales,” History of Religions 38, no. 2 (November 1998): 150—151.

20. Joshua Brown, “Historians and Photography,” American Art 21, no. 3 (Fall 2007): 9—10.

Online Journal

If an online article has numbered pages, cite them. If not, look for headings, section numbers, or paragraph numbers. Otherwise, do not cite pages.

21. Jeremy Adelman, “An Age of Imperial Revolutions,” American Historical Review 113, no. 2 (April 2008), accessed September 15, 2008, http://www.journals.uchicago.edu/doi/full/10.1086/ahr.113.2.319.

If an online article lists what it calls a “stable URL” or “permanent URL,” use that instead of the URL in your browser bar.

23. Frank P. Whitney, “The Six-Year High School in Cleveland,” School Review 37, no. 4 (1929): 70, accessed January 31, 2009, http://www.jstor.org/stable/1078814.

Print Magazine

24. William Langewiesche, “Rules of Engagement,” Vanity Fair, November 2006, 50.

If the article is part of a “department” (a recurring section with the same title in each issue), add the department name in regular type without quotation marks between the article and magazine titles.

25. Hendrik Hertzberg,“Follow the Leaders,”Talk of the Town, New Yorker, December 10, 2007, 41.

Online Magazine

If an online article has numbered pages, cite them. If not, look for headings, section numbers, or paragraph numbers. Otherwise, do not cite pages.

18.1.4 Notes for Reference Works

Reference works are sources such as encyclopedias and dictionaries; their entries usually do not have authors. (Cite an entry with an author as you would a chapter of a book; see 18.1.6.2.) If a reference work is arranged alphabetically, do not cite page numbers; list the entry in quotation marks, preceded by “s.v.” (for the Latin sub verbo, or “under the word”). If you list more than one entry in the same note, use “s.vv.”

Print Encyclopedia

If an encyclopedia has an edition number, give it.

30. Encyclopaedia Britannica, 15th ed., s.v. “Sibelius, Jean.”

Online Encyclopedia

31. Wikipedia, s.v. “Martin Luther King, Jr.,” accessed January 15, 2008, http://en.wikipedia.org/wiki/Martin_luther_king.

Online Dictionary

34. Merriam-Webster OnLine, s.v. “mondegreen,” accessed September 19, 2008, http://www.merriam-webster.com/dictionary/mondegreen.

18.1.5 Notes for Websites and Blogs

You must cite all material you find on the Internet, even if it is not published by a journal, magazine, or newspaper. In a note, you should not cite a website as a whole (www.whitehouse.gov); cite the specific document or web page that you consulted (www.whitehouse.gov/agenda/energy_and_environment/). Similarly, do not cite an entire blog in a note, but the particular posting or comment that you use in your paper.

Web Page

Websites are unpredictable, so you may have to improvise, but as much as possible include the same kind of information you need for other online publications:

✵ author, if any

✵ web page title (in quotation marks)

✵ website title, if any (in italics)

✵ sponsoring organization, if any (in regular type)

✵ access date and URL

35. Charlotte M. Porter, “Mark Catesby's Audience and Patrons,” Florida Naturalists (website), Florida Museum of Natural History, accessed May 1, 2009, http://www.flmnh.ufl.edu/naturalists/catesby01.htm.

37. “Biography,” The Charles Chestnut Digital Archive (website), ed. Stephanie P. Browner, accessed March 10, 2009, http://www.chesnuttarchive.org/classroom/biography.html.

Blog Entry

Blog entries have relatively predictable bibliographical information:

✵ author

✵ title of posting (in quotation marks)

✵ title of blog (in italics)

✵ date of posting

✵ access date and URL

38. Rhian Ellis, “Squatters' Rights,” Ward Six (blog), June 30, 2008, accessed August 1, 2008, http://wardsix.blogspot.com/2008/06/squatters-rights.html.

Web Page or Blog Comment

To cite a comment on a blog entry, begin with the name (or pseudonym) of the commenter, the title (if any), the date and time of the comment, and the words “comment on” followed by the standard entry for a blog entry or web page.

39. AC, July 1, 2008 (10:18 a.m.), comment on Rhian Ellis, “Squatters' Rights,” Ward Six (blog), June 30, 2008, accessed August 1, 2008, http://wardsix.blogspot.com/2008/06/squatters-rights.html.

Introduction, Preface, or Afterword

If someone other than the author has written a supplemental part of a book, such as an introduction, preface, afterword, or epilogue, cite it separately. Do not capitalize a generic title such as “introduction”; put it in regular type, without quotation marks.

18.1.7 Notes for Citing Citations in a Source

When you find useful information quoted or reported in a secondary or tertiary source, you should always try to locate the original source. If you cannot, you must cite both the original source and the one you actually used. Cite the original source completely, including the page number(s), then add “quoted in” (for quotations) or “reported in” (for other borrowings), followed by the complete citation for the source you consulted. Put both sources in your bibliography.

59. Louis Zukofsky, “Sincerity and Objectification,” Poetry 37 (February 1931): 269, quoted in Bonnie Costello, Marianne Moore: Imaginary Possessions (Cambridge, MA: Harvard University Press, 1981), 78.
