The Cave 1 site yielded discoveries of additional Dead Sea Scroll fragments, linen cloth, jars, and other artifacts. In November 1951, Roland de Vaux and his team from the ASOR began a full excavation of Qumran. By February 1952, the Bedouin had discovered 30 fragments in what was to be designated Cave 2. The discovery of a second cave eventually yielded 300 fragments from 33 manuscripts, including fragments of Jubilees and the Wisdom of Sirach written in Hebrew. The following month, on 14 March 1952, the ASOR team discovered a third cave with fragments of Jubilees and the Copper Scroll. Between September and December 1952 the fragments and scrolls of Caves 4, 5, and 6 were subsequently discovered by the ASOR teams. With the monetary value of the scrolls rising as their historical significance was made more public, the Bedouins and the ASOR archaeologists accelerated their search for the scrolls separately in the same general area of Qumran, which was over 1 kilometer in length. Between 1953 and 1956, Roland de Vaux led four more archaeological expeditions in the area to uncover scrolls and artifacts. Cave 11 was discovered in 1956 and yielded the last fragments to be found in the vicinity of Qumran. Caves 4–10 are clustered in an area lying in relative proximity 160 yards (ca. 150 metres) from Khirbet Qumran, while caves 1, 2, 3 and 11 are located 1 mile (1–2 kilometres) North, with Cave 3 being the most remote. In February 2017, Hebrew University archaeologists announced the discovery of a new, 12th cave. There was one blank parchment found in a jar; however, broken and empty scroll jars and pickaxes suggest that the cave was looted in the 1950s. The 972 manuscripts found at Qumran were found primarily in two separate formats: as scrolls and as fragments of previous scrolls and texts. In the fourth cave the fragments were torn into up to 15,000 pieces. These small fragments created somewhat of a problem for scholars. G.L. Harding, director of the Jordanian Department of Antiquities, began working on piecing the fragments together but did not finish this before his death in 1979. The original seven scrolls from Cave 1 at Qumran are the Great Isaiah Scroll (1QIsaa), a second copy of Isaiah (1QIsab), the Community Rule Scroll (1QS), the Pesher Habakkuk (1QpHab), the War Scroll (1QM), the Thanksgiving Hymns (1QH), and the Genesis Apocryphon (1QapGen).
