Books are a set or collection of written,
printed, illustrated, or blank sheets, made of
ink, paper, parchment, or other materials,
usually fastened together to hinge at one side.
A single sheet within a book is called a leaf,
and each side of a leaf is called a page. A book
produced in electronic format is known as an
electronic book ( e-book).
Books may also refer to works of literature, or
a main division of such a work. In library and
information science, a book is called a
monograph, to distinguish it from serial
periodicals such as magazines, journals or
newspapers. The body of all written works
including books is literature. In novels and
sometimes other types of books (for example,
biographies), a book may be divided into
several large sections, also called books (Book
1, Book 2, Book 3, and so on). A lover of books
is usually referred to as a bibliophile or, more
informally, a bookworm.
A store where books are bought and sold is a
bookstore or bookshop. Books can also be
borrowed from libraries. In 2010, Google
estimated that since the invention of printing,
approximately 130,000,000 unique titles had
been published.
