HathiTrust: Shared Digital Repository

Have you begun to follow the developments around what is emerging as the world's largest digital library? Did you know that the University of Minnesota is a charter partner in this enterprise? Now you can search the entire digital library collection using their just released "Full Text Search" at http://catalog.hathitrust.org/.

The HathiTrust is a massively scaled digital repository providing both access and preservation services for a growing number of research institutions, including all of the CIC, the University of California system, the University of Virginia, and more to be announced. Launched a little more than one year ago, the HathiTrust already contains an impressive 4,619,395 volumes or 1,616,788,250 pages (all full-text searchable) or 172 terabytes or 55 miles of shelved materials. Of these volumes 710,961 are in the public domain and are fully displayable.

The University of Minnesota Libraries are in the process of adding tens of thousands of scanned government documents into HathiTrust and anticipate adding hundreds of thousands of items over the next few years. The current catalog for searching the holdings of HathiTrust is available at: http://catalog.hathitrust.org/ . A collaborative project is underway to build a longer-term discovery interface for HathiTrust with OCLC using WorldCat Local technology.

An impressive list of other initiatives around HathiTrust, including data mining, ingest of image and audio files, understanding the relationship between digital and print repositories for the purposes of preservation, and many more are underway. Monthly progress reports are published via RSS feeds at: http://www.hathitrust.org/updates_rss . Check it out; HathiTrust is certain to be part of our "shared digital future."
