To quote Wikipedia: > A book is a medium for recording information in the form of writing or images, typically composed of many pages (made of papyrus, parchment, vellum, or paper) bound together and protected by a cover.[1] The technical term for this physical arrangement is codex (plural, codices). In the history of hand-held physical supports for extended written compositions or records, the codex replaces its predecessor, the scroll. A single sheet in a codex is a leaf and each side of a leaf is a page. ...so the book is the medium, not the abstract work of literature. A novel can be available as a book or an eBook (or, if you feel really "retro", as a scroll) the same way as a music album can be available as a vinyl record, a CD or via streaming.
