CHAPTER 23 Usenet
The major Usenet headings are:
comp - computer science related groups
sci - sciences other than computer science,
news - netnews software and general interest for netnews users,
rec - discussions of recreational activities,
soc - discussions of social topics,
talk - extended discussion of special topics (e.g. talk.politics),
misc - groups other than those listed above.
can - Canadian
clari - Clarinet (UPI) news feed
bit - BITNET lists
Groups within these headings are created by consensus of the Usenet users. In addition there are other groups such as "alt" for alternate, that are created at the whim of individual users. These groups may not be carried by all Usenet news sources. Additionally there are groups with more limited distribution, such as cle, cmh, and oh, and local groups, such as osu, cis, and uts.
