Translated book

In the following examples, the author’s name follows Eastern order (family name first) rather than Western order (family name last); the author is therefore referred to as “Liu” in a shortened note, and the name is not inverted in a bibliography entry. See CMOS 13.75 for more details.

Book Consulted in an Electronic Format

To cite a book consulted online, include either a URL or the name of the database. For downloadable ebook formats, name the format; if no fixed page numbers are available, cite a section title or a chapter or other number in the note (or simply omit). For citing a place rather than a publisher for books published before 1900 (as in the Moby-Dick example below), see CMOS 14.31.

Journal articles often list many authors, especially in the sciences. For works by two authors, list both in the bibliography and in a note (as in the Dittmar and Schemske example above). For three or more authors, list up to six in the bibliography; for more than six authors, list the first three, followed by “et al.” (“and others”). In a note, list only the first, followed by “et al.” Note that the bibliography entry for the Dror example below (which credits eighteen authors) includes an article ID in place of a page range; in a note, specific page numbers may be cited as shown (see CMOS 14.71 for details).

Web page

It is often sufficient simply to describe web pages and other website content in the text (“As of November 15, 2023, Google’s privacy policy stated . . .”). If a more formal citation is needed, it may be styled like the examples below. If a source does not list a date of publication or revision, include an access date. Alternatively, if a publicly available archive of the content has been saved using the Internet Archive’s Wayback Machine or similar service, the link for that version may be cited.

Social media content
