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? And if HT does not have them in fulltext.... still, why would it matter to your patrons if your library has a print copy or not?

If I needed/wanted to know what materials held by my library were also in the HaitTrust, then programmatically how could I figure this out? 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
