Citation Style
The following examples illustrate the notes and bibliography system. Sample notes show full citations followed by shortened citations for the same sources. Sample bibliography entries follow the notes. For more details and many more examples, see chapter 14 of The Chicago Manual of Style. For examples of the same citations using the author-date system, follow the Author-Date link above.

Journal article
In a note, cite specific page numbers. In the bibliography, include the page range for the whole article. For articles consulted online, include a URL or the name of the database. Many journal articles list a DOI (Digital Object Identifier). A DOI forms a permanent URL that begins https://doi.org/. This URL is preferable to the URL that appears in your browser’s address bar.

Bibliography entries (in alphabetical order)
Journal articles often list many authors, especially in the sciences. If there are four or more authors, list up to ten in the bibliography; in a note, list only the first, followed by et al. (“and others”). For more than ten authors (not shown here), list the first seven in the bibliography, followed by et al.

Website content
It is often sufficient simply to describe web pages and other website content in the text (“As of May 1, 2017, Yale’s home page listed . . .”). If a more formal citation is needed, it may be styled like the examples below. For a source that does not list a date of publication or revision, include an access date (as in example note 2).

For more examples, see 14.205–10 in The Chicago Manual of Style. For multimedia, including live performances, see 14.261–68.
Social media content
Citations of content shared through social media can usually be limited to the text (as in the first example below). A note may be added if a more formal citation is needed. In rare cases, a bibliography entry may also be appropriate. In place of a title, quote up to the first 160 characters of the post. Comments are cited in reference to the original post.
