There are a number of advantages to the Library’s HathiTrust Membership.
For individual users: the ability to download, rather than just view full-text public domain content, access to the full HathiTrust corpus for non-consumptive uses such as data-mining, and access to tools to facilitate those uses through the HathiTrust Research Center.
For the library: preservation services including the ability to deposit content with bibliographic and full-text searching of that content, access to a digital preservation copy of materials held in print, help in managing shared print preservation through the tracking of retention commitments of member libraries, and access to any book in the corpus for users who qualify through the Accessibility Office, enhancing the Library’s ability to provide service to students with print disabilities.
