Rare manuscript collectors often pay big bucks for a limited, signed, first-edition, or otherwise rare or unique book â€“ and can spend years tracking down a desired title. To meet the needs of exotic tome hunters, Richard Weatherford, an antiquarian book peddler, built an online database in 1982 to help hunt down hard-to-find books. Alibris offers a marketplace for retail business partners and independent sellers, providing access to over 150 million titles. In addition to being the go-to-source for rare books worldwide, Alibris also sells movies and music, and sells and rents textbooks. If they havenâ€™t found it yet, they havenâ€™t shopped Alibris.
