Books

Each sheet of the book is called a leaf and the side of a leaf is a page. In some books, the pages may be numbered sequentially, while in other books only pages with content are numbered. The life of a book depends to a large extent on the quality of paper used in the book, if poor quality paper is used it will disintegrate in a few years. Publishing is the process by which books, magazines and newspapers are printed in large numbers, so that readers can purchase them.
