# Pre-1929 Books

## Description
Books published in the US before 1929 passed into the public domain on January 1, 2024. 
We used the bibliographic catalog [Hathifiles](https://www.hathitrust.org/member-libraries/resources-for-librarians/data-resources/hathifiles/) produced by HathiTrust to identify digitized books which were published in the US before 1929. 
The collection contains over 130,000 books digitized and processed by the Internet Archive on behalf of HathiTrust member libraries. 
The OCR plain text files were downloaded directly from the Internet Archive website.

## License Issues
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](https://huggingface.co/papers/2506.05209)). If you believe you have found an instance of incorrect licensing in this dataset, please [start a discussion](https://github.com/r-three/common-pile/discussions/new) on this repository.
