Book
A book is a medium for recording information in the form of writing or images. Modern books are typically in codex format, composed of many pages that are bound together and protected by a cover; they were preceded by several earlier formats, including the scroll and the tablet. The book publishing process is the series of steps involved in their creation and dissemination.
As a conceptual object, a book refers to a written work of substantial length, which may be distributed either physically or digitally as an ebook. These works can be broadly classified into fiction (containing invented content, often narratives) and non-fiction (containing content intended as factual truth).
