Usenet is drowning in a sea of flames, spam and porn (and flames about
spammed porn), but lively, intelligent discussions can still be found
on private e-mail discussion groups. Some examples are:
AUTOCAT is an electronic forum for the discussion of all questions
relating to cataloging and authority control in libraries.
Libsoft is devoted to discussing software of particular interest to
NewJour is the New Journal and Newsletter Announcement List for new
serials on the Internet.
PubLib is a list for the discussion of issues relating to public
libraries; its subset, PubLib-Net is for discussions of the Internet
in public libraries.
Web4lib features discussions relating to the creation and management
of library-based World Wide Web servers and clients.

If you sign up for an e-mail discussion group, I strongly suggest you
download a copy of "Discussion Lists: Mailing List Manager Commands"
by James Milles of the St Louis University Law Library,
http://lawwww.cwru.edu/cwrulaw/faculty/milles/mailser.html . This
document outlines the essential commands for most mailing list
software (listserv, majordomo, mailserve, etc.) in a clear and concise
manner. Avoid embarrassment and impress your colleagues by knowing the
proper way to unsubscribe from a list.
