Hi Eric, For on-the-fly queries there is a BibAPI. http://www.hathitrust.org/bib_api The hathifiles, which is a tab-delimited output of the HathiTrust items, would well for adding links to your catalog records. http://www.hathitrust.org/hathifiles -Stephanie ________________________________________ From: Code for Libraries [[log in to unmask]] on behalf of Jon Stroop [[log in to unmask]] Sent: Friday, August 03, 2012 8:15 AM To: [log in to unmask] Subject: Re: [CODE4LIB] haititrust You can do an empty query in their catalog, and use the "Original Location" facet to filter to a holding library.
