Can't you buy a book from the shop after the security check points? Every airport I've ever been in has a few shops after you have passed the security checks.. Surely you are allowed to buy them from there?
Could be wrong though
The articles only mention what you are allowed to carry through security but it fails to mention anything purchased once in the departure lounge
