Yes, working with the HathiTrust data is interesting, to say the least. I did a bit of investigation to determine the feasibility of linking our bibliographic records to HathiTrust records. These investigations manifested themselves in three blog postings: 1. http://bit.ly/PVsKBg - Describes the overlap between the Hesburgh Libraries book collection at the University of Notre Dame and the HathiTrust. It also outlines possible services to be implemented the 'Trust. 2. http://bit.ly/OgNhCU - Here I describe how I identified and downloaded a set of 25,000 MARC records describing public domain items in both the HathiTrust and the Hesburgh Libraries' collection. 3. http://bit.ly/N0P4cl - In this posting I provide an interface for browsing a subset of the MARC records, as well as providing the means for downloading them to a local disc. What did I learn? In short, linking our records to HathiTrust records will require the coordinated skills and expertise of collection managers, catalogers, pubic service types, and systems types. I sincerely believe we can provide enhanced services against our collection -- services beyond linking -- if we figure out ways to exploit the HathiTrust. (P.S. It looks like I misspelled HathiTrust in my initial posting. Speln iz not mi 4ta.) -- Earache Least Moron
