Chicago Formatting Basics

Chicago Style has a few formatting guidelines for the notes.

  • Use superscript format and start with the number 1.
  • Place the note number at the end of the clause or sentence that refers to the source and after all punctuation except for dashes (—).
  • The first time you cite a source, provide all information about it in the note: author’s full name, title of the source, and publication information.
  • The next time you cite that source, you only need to provide the author's last name, a shortened source title, and the page number where you found the information.
  • If you cite the same source and the same page consecutive times, use the word "Ibid" (a shorted form of the Latin ibidem, meaning “in the same place”).
  • If you cite the same source but a different page number, use the word "Ibid" and follow it with a comma and the different page number.

Here are the formatting guidelines for the reference list.

  • The reference list should start on a separate page at the end of your paper.
  • Use margins no less than 1” and no greater than 1.5”.
  • Title the page Bibliography, centered at the top (no bold, italics, quotation marks, etc.).
  • References should be in a hanging indent format, meaning that the first line of each reference is set flush left and subsequent lines are indented, like this:

    Lorem ipsum dolor sit amet, consectetur adipiscing elit. Etiam at porttitor massa. In non cursus lectus. Fusce eget risus vitae tellus venenatis vestibulum a sed tellus.

  • Single-space each individual entry, but provide an extra line space between each entry.
  • Alphabetize the list by each source's first author’s last name. If there is no author, start with the first significant word in the title.
  • In titles of articles, books, and other sources, capitalize each word, except for articles (the, an), prepositions, or conjunctions, unless one is the first word of the title or subtitle.

URLs

URLs (uniform resource locators) provide the location for a source on the Internet. However, URLs can often change, which causes problems for references because we're trying to send our readers to a specific location.

DOIs

That location problem is where DOIs come in. DOI stands for digital object identifier. DOIs provide static, permanent online locations for sources. They're also noticeably shorter than most URLs, which is handy!

If you can't find the DOI on either the article or the database record page, you can look it up on CrossRef.org's Guest Query form. Scroll down to the bottom and type in the first author's last name and the title of the article.

Chicago Examples

BOOKS, including eBOOKS & REFERENCE BOOKS

The basic format is:

Footnote (First Note)

1. First_name Last_name, Title of Book: Subtitle of Book (City of Publication: Publisher, Publication Year), page numbers.

Footnote (Succeeding Notes)

2. Last_name, Shortened Title of Book, page numbers.

Bibliography Entry

Last_name, First_name. Title of Book: Subtitle of Book. City of Publication: Publisher,* Publication Year.

* Don't include the parts of publishers' names that are not required to locate the publisher. For example: The, Publishers, Co., Ltd., or Inc. However, keep the words Books, Sons, and Brothers. The word Press can be kept or omitted depending on the publisher's name. Keep Press in situations where the names could be confusing without it (Free Press) or when part of the name of a university press.

Entry in an Encyclopedia
According to The Chicago Manual of Style, "Well-known reference books, such as major dictionaries and encyclopedias, are normally cited in notes rather than in bibliographies. The facts of publication are often omitted, but the edition (if not the first) must be specified. References to an alphabetically arranged work cite the item (not the volume or page number) preceded by s.v. (sub verbo, "under the word"; pl. s.vv.)" (p. 755, section 14.247).

ARTICLES (JOURNAL, MAGAZINE, & NEWSPAPER)

The basic format is:

Journal — Footnote (First Note)

1. First_name Last_name, "Title of Article," Title of Journal Volume, no. Issue (Publication Date): page numbers.

Journal — Footnote (Succeeding Notes)

2. Last_name, "Shortened Title of Article," page numbers.

Journal — Bibliography Entry

Last_name, First_name. "Title of Article: Subtitle of Article." Title of Journal Volume, no. Issue (Publication Date): page numbers.

Magazine/Newspaper — Footnote (First Note)

1. First_name Last_name, "Title of Article," Title of Magazine or Newspaper, Publication Date, page numbers.

Magazine/Newspaper — Footnote (Succeeding Notes)

2. Last_name, "Shortened Title of Article," page numbers.

Magazine/Newspaper — Bibliography Entry

Last_name, First_name. "Title of Article: Subtitle of Article." Title of Magazine or Newspaper, Publication Date.

Notes & Exceptions:

  • Include a DOI if it's provided for electronic articles. If no DOI is available, use the periodical's homepage URL instead.
  • If you provide the URL, state it as http://www.URL.comYou don't need to provide a access date unless required by your professor.
    [See the box to the right—"URL vs DOI"—for additional information about URLs and DOIs.]
  • Chicago Style states that you only have to provide an issue number if each issue's pagination starts at page 1. However, it also states "it is never wrong to include the issue number, and doing so can be a hedge against other errors" (p. 732, section 14.180). So, if in doubt, go ahead and include it. ^_^
    To find out if the pagination continues from issue to issue, check the page numbers. High page numbers indicate continuous pagination. If you're still not sure, go to the journal's homepage and look up the issues in that volume. Find the page numbers for the first article in each issue.
  • Journal articles usually only need the year. (But some may specify a season or month.)
  • Magazine, newspaper, and newsletter articles require the year and the exact date (month or month and day).

Specific Examples:

Journal Article, Continuous Pagination, with DOI

Website

If you refer to a website in general, but not a specific part of that website, Chicago states that you can simply use an in-text citation with the website's name and URL. Here's an example:

The American Library Association's Great Websites for Kids (http://gws.ala.org/) recommends websites that are relevant for children up to 14 years of age.

If you need a more formal citation, use the example below.

Footnote (First)

Footnote (Succeeding)
2. Great Websites for Kids.
Bibliography Entry

Note that a website is the larger source. Just as book and journal titles are in italics, website titles should be in italics, too.

Blog Post

If you refer to a blog post or comment in general, Chicago states that you can simply use an in-text citation with the blog's name and date. Here's an example:

In a post on the APA Style Blog on January 24, 2013, Stefanie discussed the importance of being able to retrieve sources for APA style.
