A book is a collection of leaves of paper, parchment or other material, bound together along one edge within covers. A book is also a literary work or a main division of such a work. A book produced in electronic format is known as an e-book.
A novel (from French nouvelle, "new") is an extended fictional narrative in prose. Down into the 18th century, the word referred specifically to short fictions of love and intrigue as opposed to romances—epic-length works about love and adventures. Having become one of the major literary genres over the past 200 years the novel is today the object of discussions demanding artistic merits, a specific literary style and a deeper meaning than a true story of the same content could claim to have.
