I'm not the original poster, but I've run into this before in terms of linking library holdings to digital versions. There are a few reasons I can think of for doing this linking: 1) Your library is a selection of works that you think will best serve your readers. The library catalog is not the only place they should look, but it is a useful first place to look. 2) Other functions, like your courseware, link to your catalog; discovering additional copies in this way is useful (of course, this assumes they aren't running a service like Umlaut, right?) 3) if you don't have a good record of what was digitized from your library, HathiTrust might be the best source of that One of the big problems that I see with mass digitization and the access to those items is the loss of the role of the library in selection/collection building. I suppose if you are in a huge library like Harvard the collection is so large that it almost approaches "whatever." For smaller libraries, and with certain user populations, the mass of digitized texts is overwhelming. A library like Harvard assumes highly sophisticated users; when you combine Harvard and Michigan and California together you get a library that few of us can function in. I think the challenge for us now is to make that huge collection usable by folks other than a few experts. kc On 8/3/12 11:26 AM, Jonathan Rochkind wrote: > Not an answer to your question, but if you want to share I'm curious what your use case is where you want to limit to items your library owns. > > If HathiTrust has em in fulltext -- why would it matter to your patrons if your library has a print copy or not?

In other words, do you know of a way to query the HaitTrust and limit the results to items my library owns? --Eric Lease Morgan -- Karen Coyle [log in to unmask] http://kcoyle.net ph: 1-510-540-7596 m: 1-510-435-8234 skype: kcoylenet
