NEW for 1999 -- The used-book-search picture has changed. The keyword is consolidation. Most individual book dealer's search forms are no longer here: All their inventories are now accessible through one or more of ABE, BiblioFind or BiblioCity, not to mention those listing their stock on Alibris. I've provided BookSeek to index web pages with on-line catalogs not available in the multi-listing sites, and BookFinder.com does its great job of providing multiple search results. Unlisted independent dealers with online search forms and smaller multi-site search engines are on the more-forms page.
ABE: Advanced Book Exchange, "The INTERNET's most popular service for buying and selling out-of-print, used, rare and antiquarian books." ABE reports in February, 1999: "Currently, we have over ten million books in our database. If we don't have the book you are looking for, you can create an account for yourself (free) and leave up to 500 wants on the system. The system will then match your wants with the new books being entered into the system and notify you by email if the book you are looking for is found. In addition, our bookseller network has grown to over 4400 members from 30 countries around the world."
Bibliofind. "The world's largest inventory of books for sale. Six million old, used and rare books offered here for sale by two thousand booksellers around the world make this the largest and possibly the most interesting bookselling site on the Web."
BookSeek is an index to the on-line catalog pages of numerous book sites which are not listed at ABE, BiblioFind, or BiblioCity, and are otherwise unsearchable. BookSeek returns the catalog page of the searched-for item.
