Papyrus usually refers to a document written on sheets joined together side by side. Papyrus was like thick paper, so that people could write on it. The papyrus sheets came from the inner bark of the papyrus plant. Normally, they would roll these parchments into a scroll. This was the early form of a book. The Greek origins come for this word for papyrus, βύβλος was similar to the Greek word for a book. Thus, the English term ‘paper’ is derived from papyrus.
