I want to have an app, that helps me to lent and borrow private printed #books.
So I want to add all my books, then my friends do the same. And through the app we can see who owns what #book, arrange and track who has borrowed my books.

I found gohardcover.com/en that promises to do that, but does not work well for me.

Does anyone has an idea?
I could host a whole library system, but that is over the top.
