HathiTrust Digital Library & Research Center

A comprehensive archive of published literature available to everyone at The Claremont Colleges.



In 2016, The Claremont Colleges joined HathiTrust, a digital library partnership whose goals include preserving and providing access to digitized collections. HathiTrust aims to collaboratively build a comprehensive archive of published literature from around the world and to develop shared strategies for managing and developing digital and print holdings. HathiTrust has 2 platforms:

  1. The HathiTrust Digital Library

    • volume-level metadata
    • page-level metadata
    • part-of-speech-tagged tokens
    • token counts
