How it was discovered
Cave 5 was uncovered by the official expedition on the marl terrace near Cave 4; Cave 6 was found by Bedouin in the limestone cliff above the Wadi Qumran, close to the ruins.
Why it matters
The papyrus texts of Cave 6 show that everyday, cheaper writing material was used for community documents as well as prestige parchment for scripture.
