There are three different kinds of comic books: single issues that are usually 32 pages long are called comic books. These are printed and bound like a magazine, with the pages folded and stapled together through the centerfold. Several comics may be put together in a trade paperback. These have spines like a book and are glued together. A bigger comic book that is bound like a trade paperback but is all new, instead of collecting older comics, is called a graphic novel.
