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, 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 access to many public domain and out-of-print books.
In French, we recommend the use of “bibliothèque libre” vs “bibliothèque ouverte”
