Full entry on Wiktionary →

The codex was the historical ancestor format of the modern book. Technically, the vast majority of modern books use the codex format, of a stack of pages bound at one edge. However, the term codex is usually reserved for older manuscript books, which mostly used sheets of vellum, parchment, or papyrus, rather than paper.
