This page links you to all of the information and external resources that will help you get started accessing data from, integrating with, or contributing to the Open Library platform. Accessing Data Open Library offers free, public, low-volume Web APIs and bulk Monthly Data Dumps for accessing book and author catalog data. Here are examples of partners making use of our data in the wild. Our Web APIs are ideal for book services which need to make infrequent, real-time searches for specific books, their authors, and their availability. For projects which require importing books, authors, or covers in bulk, please kindly download our free data dumps. Client Libraries We maintain an Official (Python) Client Library for accessing data and writing bots . The are also unofficial client libraries written in Ruby and Elixir Contributing OpenLibrary.org is an open source project. If you'd like to contribute as an Open Library developer, please visit our CONTRIBUTING guide on GitHub and explore our volunteer page . Aside from the documentation here, you may also find Open Library's Docs site useful for getting started. Technologies Open Library is written in Python and uses the (now arcane) Infogami web framework, which itself is built on top of web.py Partners Are you a library, publisher, or book vendor trying to integrate your catalog with Open Library previews, lending, data, or book covers?
