Libraries
Unlike oral communication, which is often forgotten after the conversation, written communication is more permanent. It can be used to communicate an idea or a story to a large number of people, without any distortion. Books are records which may consist of written, illustrated, printed sheets which are made of paper, parchment or other material. The sheets are bound together to form the book. Since it is not possible for an individual to purchase all books, they are able to read them by borrowing the books from a library.
Books are often classified according to the binding method used. Hardcover books have a stiff binding and usually more expensive. Paperback books have flexible covers are used for cheap editions of popular books. Magazines and comics have glossy covers or dust covers.
