Dataset Card for PressBooks

A set of openly licensed books.

PressBooks is a searchable catalog of over 8,000 open access books. To collect openly licensed content from PressBooks we construct a search query to retrieve URLs for all books written in English and listed as public domain or under CC BY or CC BY-SA licenses. For each matched book, we collect its contents directly from the publicly available web version provided by PressBooks. Per-document license information is available in the license entry of the metadata field of each example. Code for collecting, processing, and preparing this dataset is available in the common-pile GitHub repo.

License Information

While we aim to produce datasets with completely accurate licensing information, license laundering and inaccurate metadata can cause us to erroneously assign the incorrect license to some documents (for further discussion of this limitation, please see our paper). If you believe you have found an instance of incorrect licensing in this dataset, please start a discussion on this repository.
