GREAT resource for old books

[Robert]

Just ran across this one:

http://www.abebooks.com/

It's basically an ebay-type "buy it now" website with many dealers with many fixed-price items. VERY extensive.

If you go to the "advanced search" (upper left of home page), you can enable Boolean logic and then use "NOT" or "AND" in the keywords.

I have no affiliation or connection to the Abebooks website or any of its dealers whatsoever. But I wanted to point it out as a public service.
