not really sure about your specific question, but along similar lines there are the standard paperback (like Pepsi's John Grisham example) and Trade paperbacks, which is what a lot of manga, american (non-newsprint) comic books, and even some of my textbooks are. I would assume that some standard novels, especially classics, can be found in TPB form too though I will admit that I haven't really looked. TPB books are printed on thicker, better paper, and the covers are usually more durable too.
