Books, catalogs, magazins etc.

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.
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.
