Startup Idea : Bookshelf- a place to rent,buy and sell books!

Seeing the ever increasing demands for books and notes at the last minutes of the exam preparations, this bookshelf in the form of APP and WEBSITE comes to rescue. This would include both the options to either buy or sell books(old and new) and also the notes(matters most during last minute). It would also have the feature to rent your books/notes for a limited time in exchange for some cash. An option to chat with the buyer/seller to bargain and fix locations for exchange could be made.
