Important Tips for Users
Log In Early: If you are a student, faculty member, or researcher at a partner university (e.g., University of Michigan, University of Wisconsin, University of Calgary, or even NYPL cardholders), always click Log In at the top right and select your institution. This unlocks complete PDF downloading and the "Collection Builder" tool to save your research lists.
Accessibility Services: Patrons with certified print disabilities can request full downloadable copies of any item in the database via the HathiTrust Accessible Text Request Service.
Bot Protection Measures: HathiTrust enforces security measures to reduce bot traffic, which can occasionally cause slowness. Logging in with your official institution or library card helps bypass these temporary blocks.
