Working in a library, I get asked by patrons, all the time how can they keep track of the books that they read so they don't check out the same book twice. 


I think I may have found their solution.  I was looking at Kindle apps available and ran across Book Catalogue; a free Android app that keeps track of all your books just by entering the ISBN number of each book.  After you enter the ISBN then all of the information automatically fills in: Picture, Title, Publisher, Author etc.

* Loaning books
* goodreads synchronization
