Open Library is an online project intended to create "one web page for every book ever published". Created by Aaron Swartz, Brewster Kahle, Alexis Rossi, Anand Chitipothu,[6] and Rebecca Malamud, Open Library is a project of the Internet Archive, a nonprofit organization. It has been funded in part by grants from the California State Library and the Kahle/Austin Foundation. Open Library provides online digital copies in multiple formats, created from images of many public domain, out-of-print, and in-print books. Its book information is collected from the Library of Congress, other libraries, and Amazon.com, as well as from user contributions through a wiki-like interface. If books are available in digital form, a button labeled "Read" appears next to its catalog listing. Digital copies of the contents of each scanned book are distributed as encrypted e-books (created from images of scanned pages), audiobooks and streaming audio (created from the page images using OCR and text-to-speech software), unencrypted images of full pages from OpenLibrary.org and Archive.org, and APIs for automated downloading of page images. Links to where books can be purchased or borrowed are also provided.
