OCLC and the HathiTrust Digital Library have developed a unique WorldCat Local user interface for discovery of items accessible through the HathiTrust Digital Library. Available at hathitrust.worldcat.org, the WorldCat Local prototype for the HathiTrust Digital Library was designed and implemented by both organizations in close cooperation as a means to further develop a shared digital library infrastructure. The WorldCat Local interface for the HathiTrust Digital Library is based on the WorldCat database, and will run along with the current HathiTrust catalog during the prototype testing period.
As a digital repository for the nation's great research libraries, the HathiTrust Digital Library brings together the massive digitized collections of partner institutions. HathiTrust offers libraries a means to archive and provide access to their digital content, whether scanned volumes, special collections, or born-digital materials. The representation of these resources in digital form offers expanded opportunities for innovative use in research, teaching and learning.
