I have been looking for an app like this for really long time – I'm a long-time user of goodreads and the goodreads app and one of my pet peeves with their app has always been the fact that there is no way to look at the books that I've designated I own. I wanted a simple, well-designed way to catalog my library in a way that would help me avoid buying duplicate books or find books on a particular subject with ease. This app goes a long way towards this goal! Would like to see a few things added - sort by author - sort by subject? - manual entry for books not found -
