Books

A book is a collection of paper, parchment or other material with text, pictures, or both written on them, bound together along one edge, usually within covers. Each side of a sheet is called a page and a single sheet within a book may be called a leaf. A book is also a literary work or a main division of such a work. A book produced in electronic format is known as an e-book. In library and information science, a book is called a monograph to distinguish it from serial periodicals such as magazines, journals or newspapers.

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. A lover of books is usually referred to as a bibliophile, a bibliophilist, or a philobiblist, or, more informally, a bookworm. A book may be studied by students in the form of a book report. It may also be covered by a professional writer as a book review to introduce a new book. Some belong to a book club.
