A nice virtual bookshelf that also has reviews / notes for all of the books is https://books.rixx.de/. It also has categories and a graph of relations between books. The code is open source as well: https://github.com/rixx/books.rixx.de

Wow, the connections component is very interesting... I might use it for my book cataloguing app.
