Bobby Bodenheimer’s article, from which this FAQ was developed, used to be posted (nominally monthly) to newsgroup comp.text.tex. The (long obsolete) last posted copy of that article is kept on CTAN for auld lang syne.
The sources of the present FAQ are available from CTAN.
This FAQ and others are regularly mentioned, on comp.text.tex and elsewhere, in a “pointer FAQ” which is also saved at http://tug.org/tex-ptr-faq
A 2006 innovation from Scott Pakin is the “visual” LaTeX FAQ. This is a document with (mostly rubbish) text formatted so as to highlight things we discuss here, and providing Acrobat hyper-links to the relevant answers in this FAQ on the Web. The visual FAQ is provided in PDF format, on CTAN; it works best using Adobe Acrobat Reader 7 (or later); some features are missing with other readers, or with earlier versions of Acrobat Reader
Another excellent information source, available in English, is the (La)TeX navigator.
Both the Francophone TeX usergroup Gutenberg and the Czech/Slovak usergroup CS-TUG have published translations of this FAQ, with extensions appropriate to their languages.
Herbert Voss’s excellent LaTeX tips and tricks provides excellent advice on most topics one might imagine (though it’s not strictly a FAQ) — highly recommended for most ordinary mortals’ use.
The Open Directory Project (ODP) maintains a list of sources of (La)TeX help, including FAQs. View the TeX area at http://dmoz.org/Computers/Software/Typesetting/TeX/
