Library and other commercial databases
When citing items such as news or journal articles obtained through a third-party commercial database that archives and offers such material whether by subscription or otherwise, follow the recommendations in the sections on the applicable publication type. In addition, include a URL, but only if the database includes a recommended stable or persistent form with the document. Otherwise, include the name of the database and, in parentheses, any identification number provided with the source. For items that do not include a publication or revision date, include an access date.

Article in an online journal
Article in a newspaper or popular magazine
Newspaper and magazine articles may be cited in running text (“As Sheryl Stolberg and Robert Pear noted in a New York Times article on February 27, 2010, . . .”) instead of in a note, and they are commonly omitted from a bibliography.
The following examples show the more formal versions of the citations. If you consulted the article online, include a URL; include an access date only if your publisher or discipline requires one. If no author is identified, begin the citation with the article title.

Cite a Website
A citation to website content can often be limited to a mention in the text or in a note (“As of July 19, 2008, the McDonald’s Corporation listed on its website . . .”). If a more formal citation is desired, it may be styled as in the examples below. Because such content is subject to change, include an access date or, if available, a date that the site was last modified.

Cite a Book:
A full reference must include enough information to enable a reader to locate the book.
Cite one or multiple authors:
Chapter or other part of a book:
Overview [Selected excerpts from the CMS, online version]
In the system favored by many writers in the humanities, bibliographic citations are provided in notes, preferably supplemented by a bibliography. The notes, whether footnotes or endnotes, are usually numbered and correspond to superscripted note reference numbers in the text; in electronic works, notes and note numbers are usually hyperlinked. If the bibliography includes all works cited in the notes, the notes need not duplicate the source information in full because readers can consult the bibliography for publication details and other information.
In works with no bibliography or only a selected list, full details must be given in a note at first mention of any work cited; subsequent citations need only include a short form.
Full citation in a note:
1. Newton N. Minow and Craig L. LaMay, Inside the Presidential Debates: Their Improbable Past and Promising Future (Chicago: University of Chicago Press, 2008), 24–25.
Shortened citation in a note:
Entry in a bibliography:
Note citations are styled much like running text, with authors’ names in normal order and the elements separated by commas or parentheses. In bibliographies, where entries are listed alphabetically, the name of the first author is inverted, and the main elements are separated by periods.
