We have resumed some on-campus services, including book pickup, virtual consultations, and fulfilling scanning/digitization requests. Many library materials are available online, but our buildings remain closed until further notice.



Connect with digitized materials from libraries around the world.

Emergency Temporary Access

Through the HathiTrust Emergency Temporary Access Service (ETAS), Harvard Library users with a valid HarvardKey may lawfully access specific digitized versions of physical books held by Harvard, due to the temporary disruption in library services. These items may be protected by copyright law but are made available through Temporary Access due to involuntary closure of the library. No further reproduction or distribution is permitted by any means without the permission of the copyright holder.

Which in-copyright books are eligible

If the work is available in digital form in HathiTrust, and Harvard has the physical book in its collection, users will usually be able to access the digital version. We say "usually" because the access is also based on matching OCLC numbers in HOLLIS and HathiTrust, for data in HOLLIS based on a 2018 snapshot. 

How It Works

  • You must Log In to HathiTrust as Harvard University.
  • “Temporary Access” books can be read only online.
  • You can Check Out a book for 1 hour. Your access will renew automatically at the end of that hour, unless another user requests the book after that hour is over. 
  • Use the Return Early button to make it available for another user. 
  • To read a book that is being used by someone else, you will need to check back periodically.

For Instructors

  • If there is a specific title you plan to use, please submit it through the Course Reserves tool and the Library will do its best to make it available to your students. This will ensure availability of materials beyond HathiTrust's ETAS window.
  • As always, early awareness of your reserve requests will be enormously helpful.

Materials currently available via the HathiTrust Emergency Temporary Access Service will continue to be free to access as long as access to the Library's physical collections remains substantially disrupted.


HathiTrust, in partnership with academic and research institutions, offers users access to millions of titles digitized from libraries around the world.

Items in the public domain can be viewed in full by all users, and items held in copyright are searchable.

HathiTrust Accessibility 

As a partner of HathiTrust, Harvard Library can provide eligible patrons with print disabilities special access to all digitized in-copyright material in the HathiTrust Digital Library.

Eligible patrons are affiliates of Harvard University who have a print disability for which access to digital copies of library books is a reasonable and appropriate accommodation.

A print disability may be defined as the inability to access print due to a visual, perceptual, or physical disability. This may include blindness, low-vision, learning disabilities, or the inability to hold a book. 

For more information, contact Harvard Library at hlproxy@harvard.edu or the local disability coordinator for your school.
