Open Library is an online project intended to create "one web page for every book ever published". Created by Aaron Swartz,〔〔 Brewster Kahle 〔(【引用サイトリンク】url = https://aaronsw.jottit.com/howtoget )〕 among others, Open Library is a project of the non-profit Internet Archive and has been funded in part by a grant from the California State Library and the Kahle/Austin Foundation. It provides access to many public domain and out-of-print books, which can be read online. ==Book database and digital lending library== 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 labelled "Read" appears next to its catalog listing. Links to where books can be purchased or borrowed are also provided. There are different entities in the database: * authors * works (which are the aggregate of all books with the same title and text) * editions (which are different publications of the corresponding works) Open Library claims to have 6 million authors and 20 million books (not works), and about one million public domain books available as digitized books. Tens of thousands of modern books were made available from 4 and then 150 libraries and publishers for digital lending. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Open Library」の詳細全文を読む スポンサード リンク
