A book is a structured set of written, visual, or audio information about a subject, presented as a piece of literature, and usually consisting of one or more authors, a publisher, and an audience. It is a product of human creative ability and is thus one of the most valuable products of human thought. The book form also offers the possibility of presenting information in a way that is easy to understand and memorize, which is essential for the development of human intelligence.

The earliest books were probably created as a record of important events or as a tool for teaching. As books became more common, they began to be used as a source of knowledge and inspiration for the written word, especially religious texts.
