Open Library Data Dumps

Open Library provides dumps of all its data, generated every month. All of the dumps are formatted as tab separated files with the following columns:

Dumps

For past dumps, see: https://archive.org/details/ol_exports?sort=-publicdate

Format of JSON records

A JSON schema for the various types is located at https://github.com/internetarchive/openlibrary-client/tree/master/olclient/schemata

Using Open Library Data Dumps

Please see this great guide by contributor on the LibrariesHacked github about how to load Open Library's data dumps into postgres to make it more useful and queriable:
