Title: As with the URL, titles should not be overly unwieldy but sufficient enough to identify the content of the site/document. If it is unclear what the title is, a "descriptive title can be used" (Rule 18.2.2(b)(iii)).
Author: Same general author rules, if there is a clear one on the site. Same for institutional authors. If there is none, add none.
According to Rule 18.2.2, “All efforts should be made to cite to the most stable electronic location available.”
The date in the parenthetical should refer only to the document cited, and should be inserted in the parenthetical. Use an exact date and appropriate abbreviations.
If there is no exact date to your document, but there is an indication of last updated, use "(last updated DATE)." If there is no date apprent anywhere, use "(last visited DATE)."
Examples:
The URL (internet address) used in your citation should point directly to the source. What does this mean? Do not give a link that, if you can, that requires further steps to find the source.
If you cannot do this, then you can provide the root URL with further description about how to find the source in the parenthetical, e.g. (follow "archive" link, then "2001-2010") (rule 18.2.2(d)).
Like anything in bluebook, the idea is to provide the easiest and most consistent way for readers to find the source.
There is sometimes confusion about when and how to cite to materials located on the internet. Below are some rules to keep in mind:
Sometimes cases/opinions are officially unreported/unpublished, but commercial databases pick them up and make them available on their systems. In that case cases may be cited to that database.
Format: party names: docket number; database identifier; court name and exact date in parenthatical.
Example:
United States v. Dewey McKay, No. 12–4001, 2013 WL 1802142 (10th Cir. Apr. 30, 2013).
