Collectors of rare manuscripts will sometimes pay thousands of dollars for a first-edition, autographed or otherwise rare book. Sometimes years are spent trying to track a specific title down. Back in 1982, Richard Weatherford, an antiquarian bookseller, had the idea to build an online database to track and help locate hard-to-find books. This idea was ahead of its time, but with the widespread growth of technology, he launched the database called Interloc in 1993. In 1997, he partnered with Marty Manley and the company evolved into Alibris. The site partners with independent sellers and offers a marketplace for retail business partners in able to provide access to over 150 million titles. Today, Alibris is much more than an online bookstore. The site also sells and rents textbooks, offers movies and music, and is the go-to source for locating rare books worldwide. Canâ€™t find it?
