20 March 2003, revised 2 August 2004. A legal professional asked about the availability of a dated Web page cache. She knew about the Internet Archive. Here are some of the answers we received:

Update: 2 August 2004. Google has returned to providing dates on cached Web pages.

Greg Notess: Google used to include both the date of the cached copy of a Web page and the date stamp from the server storing the page. It removed both dates so that the only way that I know to determine the date of the cached page, is to use clues in the content of the page itself.

A newer search engine, Gigablast, offers dated cached copies of Web pages. It also provides the date stamp of the page at the time it was cached. (Submitted by Greg Notess, Search Engine Showdown.)

Steven Cohen: For blog content, try Daypop. Click the link for "cached [date]" in the search results. (Submitted by Steven Cohen, Library Stuff.)
