My book The Only True God: Early Christian Monotheism in Its Jewish Context, forthcoming from University of Illinois Press in March of 2009, is now available for pre-order on amazon.com. A page has also been created for The Burial of Jesus: History and Faith and so I expect to be able to announce that it is available for purchase soon.
Presumably this means that you can go ahead and start recommending one or both of these books to your local public and/or university library. If you do that, it will help me more than simply buying the book yourself (although I obviously have no objection to your doing that too, if you are so inclined!) . The ISBNs and other such information are available on the amazon.com pages.
