An interesting feature set. Definitely a good start. Certainly not as full-featured as something like Booxter or Delicious Library, but has a few features that are both interesting (author quotes) and useful (bibliography) that are lacking in others.
The most pressing issue here for me is importing my collection of 56 books, which would be a pain to search for one by one. Also, the Save functionality doesn't seem to work. But again I say excellent start and I look forward to seeing where this app goes.
