Open Library
Open Library is an initiative of the non-profit Internet Archive, functioning as an editable online catalog that aims to create a dedicated web page for every book ever published, compiling bibliographic data from various library sources and user contributions to facilitate discovery and access to literature.[1] Launched in 2008, it maintains over 20 million records accessible via a wiki-style interface, allowing users to add, edit, and expand entries while integrating with the Internet Archive's broader digital preservation efforts.[1] The project emphasizes open data and software, drawing from large institutional catalogs to build a comprehensive index, and supports features like book borrowing through controlled digital lending (CDL), where digital copies are loaned in one-to-one correspondence with owned physical volumes for limited periods.[1] This model has enabled access to millions of digitized works, promoting universal availability of knowledge, though its scale relies on partnerships and grants, such as those from the Kahle/Austin Foundation.[1] Open Library's editable nature fosters collaborative improvement, distinguishing it from static databases by inviting input from librarians, readers, and authors to refine metadata and coverage.[1] Despite these achievements, Open Library has faced significant legal challenges, particularly over its CDL practices, which publishers including Hachette Book Group argued constituted willful copyright infringement by enabling unauthorized digital distribution.[2] In the 2020 lawsuit Hachette v. Internet Archive, a U.S. district court ruled in 2023 that the lending exceeded fair use, a decision upheld on appeal in 2024, leading to the removal of numerous titles from lending availability and restrictions on the program's scope.[3][4] These rulings highlight tensions between digital preservation and copyright enforcement, impacting Open Library's role in providing equitable access to out-of-print and in-copyright materials.[5]
