I've been buying some books and asking myself a few questions
Why are there several lawers over the ordinary (often plain from what I've been seeing so far) cover of the book. One is full size, containing the title and an illustration / image. Then, another smaller sized strip on top of it, usually with more "commercial" wording
But also, inside (tucked in between pages), there is a paper with information that looks more destined to the bookstore for ordering more of the book. Is it normal to get that as well when buying the book ?
