Quick bit of feedback, make the titles on your links/books/etc clickable. It wasn't obvious at the beginning that you wanted me to click the image instead of the title. Everyone has their preference, I just prefer to click titles instead of images.
I say both if possible. Little UI thing but I agree. There's no amount of clickable that's really bad in something like this.
Perfect missed that - you're right it is hard to work out as it is. Oh and yea, we wanted to see if it was useful before we made it look pretty. UI is next on the list. Thanks guys :)
