I love books. Actually, I love textbooks. There is nothing like the feeling of studying through the pages of a good textbook. But, as a real nerd, I also love computers.
Here comes the dilemma: I like paper books too much to envisaging keeping my library as Kindles (or iBooks). However, while on the go, I like to be able to browse and contemplate my library without having to bring ten boxes of books!
For all book lovers, there is an amazing website that allows you to do just that: LibraryThing. LibraryThing allows you to keep a virtual collection of all your books, classified by category, tags (and many more things like a forum where you can discuss your beloved novels with other users, groups where user with similar taste can exchange tips, review books, etc...).
I have created a group for iOS and Mac OS X developers. I have also inserted a first topic: "Best iOS development books". The URL to the group is the following: http://www.librarything.com/groups/iosandmacosxdevelope (yes, there is no 'r' in developer, the URL has been generated by LibraryThing like that, ugly I know...)
