How does HathiTrust Emergency Temporary Access Service (ETAS) work? Why can’t I check out a physical copy of a HathiTrust item if it is in the Libraries’ collections?

Through the HathiTrust Emergency Temporary Access Service (ETAS), current Mason students, faculty, and classified staff have full-view access to items in the Libraries' collections which match a digitized copy in HathiTrust. Read more about the HathiTrust ETAS program and how to access it here. Note: The HathiTrust ETAS program is available while the Libraries' stacks are closed; once the stacks reopen to our community (anticipated Fall 2021), the program will be suspended.


Items available through the ETAS can be checked out for 1 hour. If you are still actively looking at the book and no one else is attempting to check it out, the book will be renewed automatically.


Each institution participating in the HathiTrust ETAS has access only to the number of digital copies that match the institution's physical holdings. For example, if the Libraries holds only 1 print copy on the shelves, then only 1 user affiliated with Mason can access the digital book in HathiTrust at a time. Please be courteous, and return books as soon as you're done with them.


The Libraries is aware of the potential inconveniences of this system; however, our participation in the ETAS program provides access to approximately 350,000 titles digitally - which is crucial during the current pandemic and expanded virtual learning environment - that would otherwise be unavailable to those unable to come to campus.
