**Accessing Data** |

Open Library offers free, public, low-volume [**Web APIs**][2] and **bulk** [**Monthly Data Dumps**](/data) for accessing book and author catalog data. Here are [examples](/developers/api#api-partners) 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. |
