iOS Universal Books
For anyone that reads, this is the ultimate swiss knife of book collections.
With iBibliotecary you can track all of your books, to whom you loan them, if you have read them, synopsis, name, location, everything you'll ever need.
And you don't need to fill all the book's information by yourself, as iBibliotecary will search for the information by you.
When you finish, you can sync your catalogue with iBibliotecary's desktop versions (available for Windows, Linux and Mac OS X).
Corrected bug that made iBibliotecary crash randomly on iOS 6.
Updated Amazon search to their newest interface.
Dropped support for original iPhone and iPhone 3G.
=== IMPORTANT NOTICE ===
If you are using an original iPhone, an iPhone 3G, or an iPod Touch 1st or 2nd generation do not update.
