Bill-
   Check you local library for *Bookman's Price Index: A Guide to the Values
of Rare and Out-of-Print Books*. It is an authoritative source for prices of
35,000 out-of-print and rare books. It includes information from dealers in
the U.S., Canada, and Great Britain. *American Book Prices Current*,
*Bookman's Guide to Americana*, and U.S.-Iana will also give you the same
type of information. Forgive me if these sources are well known by the
members
of the list. I am a librarian and can't help myself.
