There are two items here:
A copy of the alt.binaries.sounds.anime FAQ

and a bit of a.b.s.anime posts logging done after Onakra stopped his logging.
Hopefully this post logging will rise from the dead like a phoenix in a mostly automated format in the not _too_ distant future and then again include Onakra's logging (2001 - oct 2003), this bit of logging (oct 2003 - nov 2003) and most of the posts since then (raw newsgroup article list data is being collected/stored).
