Developers / API


Open Library has developed a suite of APIs to help developers get up and running with our data. We encourage interested developers to join the ol-tech mailing list to stay up-to-date with the latest news, or dive in with our own development team at our bug tracker or our GitHub source code repository.

APIs

Open Library has a RESTful API, best used to link into Open Library data in JSON, YAML and RDF/XML. There's also an earlier JSON API, which is deprecated now. This is only retained for backward compatibility.

You can also return bibliographic data by simply adding an .rdf/.json/.yml extension to the end of any OL bibliographic identifier. There are also links on pages to RDF and JSON versions of Works, Editions and Authors.

Read APIs

Access to Records in Bulk

Our API 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 info@.

Open Library in the Wild

Several developers are creating amazing things with the Open Library APIs:

Are you using the Open Library APIs? We'd love to hear about it! Please email us at info@.
