MIT maintains an FTP site (ftp://rtfm.mit.edu -- "RTFM" being anacronym for "Read The F***ing Manual") which is often considered the official site for most newsgroup FAQs. You can check many of them out at Usenet by Hierarchy or via the Ohio State Hypertext versions of SOME of them.

There are also many mirrors of MITs site, here is a sampling:

An Index to the Utrecht University Computer Science Department's Software Archives. This isn't software in the commonly applied sense of Programs -- it is actually a data archive. In addition to the link to the FAQs above (as well as a search engine and newsgroup-based list), this page also offers links to CERT (Computer Emergency Response Team) Advisories and some other useful stuff.

There are also some programmer FAQs listed in my Programmer Links page.
