Are the News Groups Archived Anywhere?

The Usenet Linux news groups are archived at
http://groups.google.com/.

ftp://metalab.unc.edu/pub/Linux/docs/linux-announce.archive contains
archives of comp.os.linux.announce. These are mirrored from
ftp://src.doc.ic.ac.uk/usenet/, which also archives comp.os.linux,
comp.os.linux.development.apps, and comp.os.linux.development.system.
