The collection contains a number of papyri, many of which were acquired from Professor Sayce and Rev. Greville J. Chester towards the end of the nineteenth century, and through the former's bequest of 1933.
The Library also took possession, in 1908, of the whole of the find made during the excavations at Deir el-Bala'izah by Flinders Petrie in 1907. The material dates from the sixth to eighth centuries, and represents the remains of the library and charter-room of the Coptic monastery of St. Apollo at Deir el-Bala'izah, near Rifeh, in Egypt's Western Desert. The find contains fragments of c. 3000 texts, mainly on papyrus, and includes Biblical manuscripts, liturgical books, homilies, acts of Egyptian saints, as well as taxation receipts and monastic accounts.
There are also 94 manuscripts of George Horner, comprising collations and notes etc.
