Hardcover books have a stiff binding. Paperback books have cheaper, flexible covers which tend to be less durable. An alternative to paperback is the glossy cover, otherwise known as a dust cover, found on magazines, and comic books. Spiral bound books are bound by spirals often made of metal. Examples of spiral bound books include: teachers manuals, and puzzle books (crosswords, sudoku).

Publishing is a process for producing books, magazines, newspapers, etc. pre-printed for the reader/user to buy, usually in large numbers by a publishing company. Such books can be categorized as fiction (made-up stories) or non-fiction (information written as fact). A book-length fiction story is called a novel.

Publishers may produce low-cost, pre-publication copies known as galleys or 'bound proofs' for promotional purposes, such as generating reviews in advance of publication. Galleys are usually made as cheaply as possible, since they are not intended for sale.
