Authorized Text, Exemplar, and Scriptorium

Authorized Text (Archetypal Manuscript): A text used to make other copes.

Exemplar: The authoritative text of a New Testament book from which other copies were made; if in a scriptorium, an archetype; if in a congregation or home, a master-copy.

Scriptorium: A scriptorium is a room where multiple scribes or even one worked to produce manuscript(s). A lector would read aloud from the exemplar, as the scribes(s) would write down the material.
