is a vertical search website
that helps readers buy books online. The site's meta-search
engine scans the inventories
of over 100,000 booksellers located around the world. Among the books from sellers whose inventories are indexed, users can find the lowest price for a book of their choice from over 150 million volumes available for sale, and purchase titles directly from the bookseller, without a markup.
The search engine is focused primarily on Dutch, English, French, German, Italian, and Spanish language titles.
BookFinder.com was founded in 1997 by Anirvan Chatterjee, then a student at the University of California, Berkeley
; it was one of the earliest vertical search engines for books online.
Originally known as MX BookFinder,
it was relaunched as BookFinder.com in 1998 and established as a standalone company based in Berkeley, California
