It's become difficult to get books "valued" at over $1,000, which is basically any out of print book now thanks to Amazon's bogus valuations.

I peeked at your profile and, well, do you know about OhioLINK? I think maybe you're holding it wrong.

The last time I grabbed something rare via OhioLINK it was a twenty year old instructor's manual that accompanies a calculus textbook I own, which they shipped all the way from across the state from some little college's library.

Your request for Asimov's annotated Paradise lost. Text by John Milton, notes by Isaac Asimov. was successful.

I fully expect this to go through but I'll make a note here if it doesn't. And hey, you should totally try this yourself, it's an interesting book.
