Many TEX-related books are available through TUG, the TEX Users Group.
They also produce an excellent magazine called TUGboat.
Anybody planning to use TEX a lot is strongly advised to join.
The ``TEX Users Group'' item in the Help menu explains how to get in touch.
If you have access to the Internet then another good source of help and
information about TEX-related topics is the comp.text.tex newsgroup.
