The Landfield Group maintains an archive of publicly available material. The archive is available here as well as via FTP from ftp.landfield.com. The following is a sampling of what is available.
Internet RFC/STD/FYI/BCP Archives
The Internet RFC, FYI, STD and BCP documents have been converted to hypertext to make them easier to read. The archive also supplies search facilities in order to allow you to look things up quickly.
Internet FAQ Archives
Documents covering Frequently Asked Questions are posted regularly to Usenet newsgroups. These documents cover a wide range of topics with over 1000 authors posting more than 3000 different FAQs. In order to make the documents more useful, the Hypertext FAQ archive has had all appropriate references hyperlinked. There is also an extensive full text search facility. If you're looking for an answer to a question, this is a great place to start.

Usenet Moderators Archive
landfield.com is the home of the Usenet moderators archive. The archive contains tools written and used by moderators of Usenet newsgroups. Moderation of newsgroups is transcending Usenet as many organizations begin using Usenet software for internal use.
The contents of this archive have been generously made available in a "AS IS" condition. Many of the sources, scripts and yes, documents are not as pretty as the individual moderators may like but they work and are being used. The idea is that the archive is a snapshot of tools used. They are made available so that others can see how it is done and potentially get a copy as a starting point for their newsgroup's required modifications.
Usenet Standards Format Update Working Group
The UseFor working group is following up on the work done by Henry Spencer with "Son-of-RFC1036". The group is extending the Usenet news formats and is working towards approval of a new Usenet news RFC.
FAQ Author Support Center
Assistance and information is available to those that wish to write and post Usenet Frequently Asked Questions (FAQs). The faq-maintainers list archives are also available.
Home of the Usenet newsgroup comp.sources.misc
