Hi Eric, There are a couple of answers to your question, depending on whether Notre Dame is currently participating in ETAS or not. If you are, or ended your participation fairly recently, you should have a relatively recent overlap file sent from Hathi to your ETAS representative. Those files are based on your institution's holdings files that you sent them, and so already are only a list of what you own. From an overlap file, you can grab catalog identifiers and access statements. Anything in that file that says 'allow' in the access column is 100% open to the world (unless the 'rights' column says 'pdus' in which case it's only open in the US...), and back in the spring I got lists of all of our titles that were open or temporarily open by importing lists of identifiers with various criteria into our catalog to create itemized sets. That's the quick way. If you don't have a recent overlap file from HT, there's a perl script on GitHub <https://github.com/BCDigLib/BC-HT-IA-Ingests/blob/master/bc.pl> that we at Boston College use to turn the monthly published HathiFiles <https://www.hathitrust.org/hathifiles> from lists of everything in Hathi to lists of everything contributed by BC. You ought to be able to modify that so that it's picking out Notre Dame items instead, but since it's an inherited script and I don't really know Perl, I'm afraid I can't tell you exactly how. From that point you'd have a list of everything in HathiTrust contributed by Notre Dame, which you can poke around at programmatically and again, identify everything that's got an 'allow' tag in the 'rights' column, and go from there. That one's a little easier in that you don't have to get the catalog involved to get titles, but I'll warn that given the way we use the workflow, I can't guarantee you won't wind up with some munched diacritics. Hope that helps!
