English

Noun

codex (plural codices or codexes)

• An early manuscript book.
• A book bound in the modern manner, by joining pages, as opposed to a rolled scroll.
  • ✤ From its inception, the index has provided a window onto the history of the book, for it took the advent of a particular type of book — the codex, a sheaf of pages fastened along one edge — to make an index a practical possibility. The progenitor of the modern bound book, the codex gradually supplanted the scroll, a medium inimical to the indexer’s art.¹
• An official list of medicines and medicinal ingredients.

Etymology

Borrowed from Latin cōdex, variant form of caudex (“tree trunk, book, notebook”); compare caudex (in botany). Doublet of code.
