José O’Callaghan, “Papiros neotestamentarios en la cueva 7 de Qumran?” Biblica 53 (1972), pp. 91–100. 7Q5, supposedly the best example, is said to offer letters from Mark 6:52–53—20 legible letters in all. The texts are, however, extremely difficult to read, and other identifications have been proposed for them. For the texts and other bibliography, see Florentino García Martínez, “Lista de MSS procedentes de Qumran,” Henoch 11 (1989), p. 223.
