Came here to also recommend LibraryThing. It's been around for 14 years, and the community has lots of similar situations to OP's. Probably a good place to look up anecdotal evidence for this kind of project, too. LibraryThing also hooks into [TinyCat](https://www.librarycat.org/ https://www.librarycat.org/) which can make your database more like a library's.
