Iowa State University became a partner institution of the HathiTrust in 2013. As a partner institution, ISU affiliated users of the HathiTrust can download entire copies of full-text materials contained in the HathiTrust collection that are in the public domain. Currently, 3,324,547 volumes (~31% of total) are in the public domain.

Another advantage to being a partner institution is ISU students, faculty and staff can save materials to their own collections for quick and easy retrieval.

Welcome!  This Guide introduces HathiTrust, provides strategies for effective searching of this vast resource, and describes the types of material you can expect to find here.

HathiTrust is a huge college of over 15 million digitized full text books, journals, and other resources.  Their collections include both full text materials that are open access / out of copyright, and records for copyrighted resources. We also have information about the HathiTrust Print Disability Access program, and how eligible users with print disabilities can work with ISU library staff to access copyrighted material from HathiTrust.


Anyone can access HathiTrust and view the resources but only those affiliated with partner institutions can download public domain materials in their entirety. Iowa State University is a partner institution so all faculty, staff and students have this ability.


All you need to login to the HathiTrust is your NetID and password. (Logging in with your ISU ID number and library password will not allow access to the full-text materials provided by the HathiTrust


HathiTrust materials are discoverable in Quick Search and will show up as an Online Resource. You can also go directly to and search for materials or just browse the collection. Either way, viewing is simple and available to anyone but you will need to login in order to download text or to save materials to your own HathiTrust collection.
