Open Library offers a suite of APIs to help developers get up and running with our data. This includes RESTful APIs, which make Open Library data availabile in JSON, YAML and RDF/XML formats. There's also an earlier, now deprecated JSON API which is preserved for backward compatibility.
-
Books API - Retrieve a specific work or edition by identifier
-
Authors API - Retrieve an author and their works by author identifier
-
Subjects API - Fetch books by subject name
-
Search API - Search results for books, authors, and more
-
Search inside API - Search for matching text within millions of books
-
Partner API - Formerly the "Read" API, fetch one or more books by library identifiers (ISBNs, OCLC, LCCNs)
-
Covers API - Fetch book covers by ISBN or Open Library identifier
- Recent Changes API - Programatic access to changes across Open Library
Every Page on Open Library is an API
You can return bibliographic data by simply adding an .rdf/.json/.yml extension to the end of any OL bibliographic identifier, for instance: https://openlibrary.org/works/OL15626917W.json or https://openlibrary.org/authors/OL33421A.json. Many pages, such as the Books, Authors, and Lists, will include links to their RDF and JSON formats.
Bulk Access
Our APIs should not be used for bulk download of Open Library data. If you want a dump of complete data, please read about your Bulk Download options, or email us at openlibrary@archive.org.
Questions
We encourage developers to ask questions by opening issues on Github and on our gitter chat channel.
Friends using Open Library APIs
Several developers are creating amazing things with the Open Library APIs:
-
Trove by the National Library of Australia
Trove is a new discovery experience focused on Australia and Australians. It supplements what search engines provide with reliable information from Australia's memory institutions. The system hits Open Library when public domain books turn up in searches, and displays links to Open Library.
-
Koha
Koha is an open source library system for public libraries that includes catalog searches and member organizing. It uses Open Library covers, displays OL related subjects, and lendable eBooks using the Read API.
-
Evergreen
Evergreen is highly-scalable software for libraries that helps library patrons find library materials, and helps libraries manage, catalog, and circulate those materials. It uses Open Library for covers, tables of contents, with plans to expand into other areas.
-
read.gov by the Library of Congress
OK, this isn't exactly Open Library, but it's still awesome! The Library of Congress have modified the Internet Archive's Book Reader to sit perfectly within their Rare Books Collection site.
-
OpenBook WordPress Plug-in by John Miedema
OpenBook is useful for anyone who wants to add book covers and other book data on a WordPress website. OpenBook links to detailed book information in Open Library, the main data source, as well as other book sites. Users have complete control over the display through templates. OpenBook can link to library records by configuring an OpenURL resolver or through a WorldCat link. OpenBook inserts COinS so that other applications like Zotero can pick up the book data.
-
Umlaut by Jason Ronallo
Umlaut is a middle-tier OpenURL link resolver that adds functions and services to commercial link resolving software.
-
Virtual Shelf by Jonathan Breitbart and Devin Blong (UC Berkeley School of Information)
The Virtual Shelf is a visualization created by two students at the UC Berkeley School of Information. The project includes the student's master thesis, with research into the searching and browsing patterns of library patrons. The Open Library RESTful API was utilized during the project as a source of metadata for the user interface.
-
RDC UI Toolkit by Rural Design Collective
This group created a suite of tools that facilitates the creation of localized user interfaces for public domain books. The RDC used the Open Library Covers API and the Internet Archive Book Reader in their online demonstration customized for the OLPC XO.
