Another alternative on the fediverse is NeoDB. I’m trying that one out for the time being. Its interface is pretty barebones and could use some work, but it’s nice because you can track more than books.

Interlibrary Loan isn’t available everywhere (at least back when I used to work at a library ~10 years ago it wasn’t). If it is, it often has an associated fee (usually at least shipping fees, sometimes an additional service fee). I think the common exception to that is public university libraries.

But I can’t pirate copyrighted materials to “train” my own real intelligence.
