Types of stitched or sewn bindings:
A sewn book is constructed in the same way as a hardbound book, except that it lacks the hard covers. The binding is as durable as that of a hardbound book.
Stapling through the centerfold, also called saddle-stitching, joins a set of nested folios into a single magazine issue; most comic books are well-known examples of this type.
Magazines are considered more ephemeral than books, and less durable means of binding them are usual. In general, the cover papers of magazines will be the same as the inner pages (self-cover)[22] or only slightly heavier (plus cover). Most magazines are stapled or saddle-stitched; however, some are bound with perfect binding and use thermally activated adhesive.
