Script for book data scrapping

[yuchdev]

I gratefully accept any help with this task. I'm planning to do data scrapping on the most popular sources and publishers, Amazon, Leanpub, O'Reilly, Packt. Create a hash on every existing book, so that not to add it twice. Add new books as Github Issues. An interesting task, but I lack experience in Web Scrapping and don't have much time at the moment.
