I think you must buy but I am not sure. It is a great place to see and hangout little bit tho. They have very nice small cafeteria.
Not like library, you can read the books in the store Cafe, but you can't take them out. It's a very good place to read or study.
*borrow... And no you cant borrow books. You are more than welcome to stay all day and read.
You can read and check some of book while inside the book store but you can't barrow. It is like a Barnes and Noble
