Brian,
I know you stated repeatedly that you aren't interested in the NT but perhaps you could point us in the direction of scholarly determination of the authorship of the various books in the bible.
purpledawn,
I liked this book on the OT:
Who wrote the Bible? Author: Friedman, Richard Elliott.
Publisher, Date: [San Francisco] : HarperSanFrancisco, [1997], c1987.
ISBN: 0060630353 - Description: 299 p. : ill., maps ; 21 cm.
The Yahoo Group: JesusMysteries
has wide ranging discussions of the materials in the first 4 centuries of Christianity. They go into a lot more detail than I've seen here or actually care to follow but it's free and you could take a look at it. It's very activity but well moderated so folks posters rarely get out of hand.
