Charlie, thank you.

Downloading the latest & greatest HathiTrust full extraction catalog dump and "grepping" all the lines matching ^innd gives me a (short) list of the items contributed by Notre Dame. I can then use the HathiTrust Data API to actually get the PDF and OCR versions of the items. Moreover, I can use a similar process for other libraries. Even more, if desired, I could pour the full extraction into a database, index it, and then create a rudimentary HathiTrust search. 

In any event, this works very very well. Again, thank you.
