This week, we take a closer look at the HathiTrust Digital Library. This collection is likely the most oriented towards academic researchers, largely because it was the product of 13 universities that made up the Committee on Institutional Cooperation (renamed the Big Ten Academic Alliance last year) and the University of California.
The Trust began in 2008 as the result of the digitization of “orphan books,” which started in 2004 by the Google Books Library Project and now consists of a partnership of 60 research libraries located in Canada, Europe and the U.S. (See www.hathitrust.org/community). The University of Michigan currently provides the infrastructure on which the digital content resides. The collection includes 15 million volumes, of which about half are books. Of those 7.5 million books, 5.8 million are in the public domain. Continue reading HathiTrust Digital Library, a major source of open scholarship with legal issues seemingly behind it
Discovery services continue to add full text content. Two press releases this week announced that HathiTrust Digital Library content is now searchable through the EBSCO and OCLC WorldCat discovery services. Below are some snippets from each press release:
EBSCO: HathiTrust includes the digitized collections of more than 50 major research institutions and libraries. The HathiTrust Digital Library combines the resources of the partner institutions in order to preserve these vast digital collections. A large portion of the digital library is made up of books that have been digitized in agreement with Google Books. Additional content includes digitized content from partners including university presses and individual library’s collections. The enormity of HathiTrust’s digitized repository significantly expands the search experience for discovery users. Although HathiTrust offers a standalone search service, through EBSCO Discovery Service, users will soon be able to search HathiTrust’s collection of over 8.5 million digitalized volumes including over 9.5 million volumes, including more than five million book titles and 250,000 serial titles as part of EDS. Enabling the search of full text as part of EDS revitalizes these records by bringing them to the forefront of the user’s search experience and allows them to discover more of the library’s collection.
OCLC: Under this new agreement, OCLC will be able to integrate the full-text index of HathiTrust collections into services such as WorldCat.org and WorldCat Local. Following integration of the full-text index, users will be able to search beyond bibliographic records to include the full text of these cooperatively built library collections in their searches.
Content from the HathiTrust Digital Library complements member libraries’ collections already in WorldCat. Through a single search of WorldCat.org or WorldCat Local, users will easily find HathiTrust resources and other materials available in their own collections, and in the collections of thousands of libraries around the world that are part of the OCLC cooperativ
DUBLIN, Ohio, January 18, 2011OCLC and the HathiTrust have developed a unique WorldCat Local user interface for discovery of items accessible through the HathiTrust Digital Library. The WorldCat Local prototype (http://hathitrust.worldcat.org) 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. Continue reading HathiTrust and OCLC Develop WorldCat Local Prototype
There is an interesting visual search feature in the HathiTrust Digital Library. Call number, language, and date, for both the entire HathiTrust collection and public domain works are available. The visualizations are colorful and created in flash on the screen. Roll over a piece of the pie and stats will appear, (i.e. DS – History of Asia, 157616 items), click on the pie piece and results for that variable will be displayed.
Here’s a HathiTrust sample chart – but not interactive.
Thanks to Gary Price from Resource Shelf for showing me this cool feature.
Great news for eBook exposure! In an effort to maximize the visibility and value of libraries’ full collections, OCLC is adding records to WorldCat that represent digitized books from the Google Books Library Project and the HathiTrust Digital Library to provide greater access to and increased visibility of these rich digitized collections.
OCLC is working with libraries, Google and the HathiTrust to derive new MARC records that represent these digital collections based on the rich collection of print records contributed to WorldCat by the OCLC membership over the last 40 years. Searchers will begin seeing these records in WorldCat immediately. OCLC will continue to add records for these collections to WorldCat on an ongoing basis.
