A book is a set 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.[2]
The methods used for the printing and binding of books continued fundamentally unchanged from the 15th century into the early years of the 20th century. While there was of course more mechanization, Gutenberg would have had no difficulty in understanding what was going on if he had visited a book printer in 1900.
Gutenberg's invention was the use of movable metal types, assembled into words, lines, and pages and then printed by letterpress. In letterpress printing ink is spread onto the tops of raised metal type, and is transferred onto a sheet of paper which is pressed against the type. Sheet-fed letterpress printing is still available but tends to be used for collector's books and is now more of an art form than a commercial technique (see Letterpress).
Modern paper books are printed on papers which are designed specifically for the publication of printed books. Traditionally, book papers are off white or low white papers (easier to read), are opaque to minimise the show through of text from one side of the page to the other and are (usually) made to tighter caliper or thickness specifications, particularly for case bound books. Typically, books papers are light weight papers 60 to 90 g/m² and often specified by their caliper/substance ratios (volume basis). For example, a bulky 80 g/m² paper may have a caliper of 120 micrometres (0.12 mm) which would be Volume 15 (120×10/80) whereas a low bulk 80 g/m² may have a caliper of 88 micrometres, giving a volume 11. This volume basis then allows the calculation of a books PPI (printed pages per inch) which is an important factor for the design of book jackets and the binding of the finished book. Different paper qualities are used as book paper depending on type of book
Books are the things, which are needed to increase the knowledge of the individual or of any.
