Electronic Resources (Rule 18)

Direct Citations to Internet Sources

Cite directly to an internet source that cannot be cited according to another Bluebook rule. The citation should include the title, pagination, publication date, and the URL.

N.B.: Former versions of the Bluebook required that URLs be preceded with “available at”—that is no longer the case. The URL simply follows a comma at the end of the citation.

Model

Author, Title, Main Page Title, (Date or Date and Time), URL.

(1) Typeface the title or party name as you would for a normal citation. Do not underline the URL.

(2) If an author is unclear, a title alone may be used, unless there is a clear institutional author [rule 18.2.2(b)].

(3) Only pinpoint cite, if a page number appears in the document itself, e.g. PDFs, and not screen numbers [rule 18.2.2(g)].

(4) Dates. Indicate a year if the date clearly refers to the material cited, else use "last visited X date " in the parenthetical [rule 18.2.2(c)].

(5) URLs. The URL should take the reader directly to the page, with no intervening links in between. If the URL is long and unwieldy, then indicate the root URL with a parenthetical explaining how to access the information [Rule 18.2.2(d)].

A digital copy of a printed source may be cited, so long as it is authenticated, official, or an exact copy of the printed source; otherwise, the printed source must be cited [Rules 18.2 & 18.2.1].

 

These citations do not need to include a URL unless: they are obscure; citation to a URL will improve access to the cited source; or if the online source shares enough characteristics of the print source that it could be fully cited according to another rule, in which case the URL can be added to the end of the citation [Rule 18.2.1(b)].
