    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:


	
     type - type of record (/type/edition, /type/work etc.)

 
	
     key - unique key of the record. (/books/OL1M etc.)

 
	
     revision - revision number of the record

 
	
     last_modified - last modified timestamp

 
	
     JSON - the complete record in JSON format
 


Dumps:


	
     editions dump (~ 5.7G)

 
	
     works dump (~ 1.6G)

 
	
     authors dump (~ 0.3G)

 
	
     all types dump (~ 7.8G): includes editions, works, authors, redirects, etc.

 
	
     complete dump (~ 18.3G): also includes past revisions of all the records in Open Library
 


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
