Bluebook Citation of Internet Sources

The following is reprinted from The Bluebook: A Uniform System of Citation (18th ed. 2005).

18.2.3 Direct Citations to Internet Sources

(a) Generally.  An Internet source may be cited directly when it does not exist in a traditional printed format or on a widely available commercial database, or when a traditional printed source, such as a letter or unpublished dissertation exists but cannot be found and is so obscure that it is practically unavailable. In either case, the title, pagination, and publication date should be reported as they appear on the Internet. The Internet URL should then be appended directly to the end of the citation (i.e., not preceded by available at or at). The citation should be formatted by analogy to rules 10-17 and rules 19-21 and based on the following principles. Below is an example of a direct citation to an internet source:

Yonatan Lupu, The Wiretap Act and Web Monitoring: A Breakthrough for Privacy Rights?, 9 Va. J.L. & Tech. 3, ¶ 7 (2004),

Use Colum. Sci. & Tech. L. Rev. as the abbreviation for the Columbia Science and Technology Law Review.
