Chicago: Online and Nonprint Sources (Notes and Bibliography System)

Presented below are a number of examples of citations for online resources as they may appear in a bibliography using the Notes and Bibliography system. The examples are meant to be illustrative and do not encompass every possible situation. A few points to keep in mind:

Unlike other citation styles, Chicago style does not require the listing of an access date for online sources. A date may be provided if a source's content is likely to change. Turabian style, on the other hand, does require an access date.
If information normally included in a citation is missing, unknown, or not provided, that information should be omitted from the citation.
Online versions of print materials are cited identically to their print counterparts; the URL of the online version is then appended to the citation following the citation's final period.
A period is always placed at the end of a citation, even if the last element of the citation is a URL.

For general guidelines on citing electronic sources, consult The Chicago Manual of Style, sections 17.4-15. Citation rules for electronic sources appear under the relevant source types (e.g. books, periodicals, etc.). Consult with a reference librarian for additional assistance.
