Alibris

Alibris is an online store that sells new books, used books, out-of-print books, rare books, and other media through an online network of independent booksellers.

Alibris was founded in 1997 by Martin Manley and incorporated in 1998. It grew out of Interloc, an online company founded by antiquarian bookseller Richard Weatherford in 1994. Interloc was one of the earliest successful efforts to centralize used book data online. It remained a private network until 1996, when the company launched its website. The company was backed by venture capital until 2006, when it was purchased by Oak Hill Capital Partners, a private equity firm. In February 2010, Oak Hill Capital Partners bought Monsoon and merged it with Alibris with Monsoon Commerce owning Alibris. As of February 2017, Alibris is now owned by AM Holding Inc. (formerly Monsoon Commerce Inc.)

Booksellers list their inventories on Alibris which in turn offers the books on its retail website, a separate library services site, and business-to-business partners such as Barnes & Noble, Books-A-Million, and Chapters Indigo. It also offers services in the UK with the Waterstones market place. It offers more than 150 million books from a network of over 15,000 booksellers in 65 countries.

Most sales made through Alibris are fulfilled by the bookseller directly to the end customer. Sales to libraries or other institutions or books needing transoceanic shipping are consolidated in a distribution center in Sparks, Nevada. Alibris also has a similar network for music (albums, cassette tapes, and CDs) and movies (VHS or DVD).

Alibris allows customers to buy and sell at the same time. Alibris charges a starting fee that varies based on what is being sold and what kind of commission is charged.
