The word manuscript derives from Latin manus = ‘hand‘ and scribere = ‘to write’ and means a handwritten document, in a portable format, written on papyrus (mainly used in antiquity), parchment (widespread after the 3rd century AD) or paper (since the 12th century AD). Inscriptions are normally excluded from this definition. As a format, the codex is generally used for Western manuscripts since the 3rd century AD, replacing the scroll. Medieval manuscripts are often composite: they are composed of several "codicological units", that may date from different periods.
Before the invention of the printing press (mid 15th century), written texts were transmitted through copying of manuscripts. Most manuscripts carry many texts and will therefore be used as witnesses for the study of several textual traditions.
The term manuscript is also used for the final draft of a modern text that is sent to the printer, no matter whether it is hand-written or not.
