Editing Papyrus (section)

=== Varying quality ===
Papyrus was made in several qualities and prices. [[Pliny the Elder]] and [[Isidore of Seville]] described six variations of papyrus that were sold in the Roman market of the day. These were graded by quality based on how fine, firm, white, and smooth the writing surface was. Grades ranged from the superfine Augustan, which was produced in sheets of 13 digits (10 inches) wide, to the least expensive and most coarse, measuring six digits (four inches) wide. Materials deemed unusable for writing or less than six digits were considered commercial quality and were pasted edge to edge to be used only for wrapping.<ref>{{Cite journal|last=Lewis|first=N|year=1983|title=Papyrus and Ancient Writing: The First Hundred Years of Papyrology|journal=Archaeology|volume=36 |issue=4|pages=31–37}}</ref>
