Discovery and MARC Records

We provide an automatically generated cumulative file of MARC (Machine-Readable Cataloging) bibliographic records and a .csv file for content in the Open Textbook Library. New titles are added throughout the month. If we delete a textbook record, we will create a deleted list and post it below.

Open Textbook Library records are in the public domain and available under a Creative Commons CC0 license.
