This final chapter follows the journey of Jerban student Sālim Bin Yaʿqūb (d. 1991) from Tunisia to Egypt, where he lived at the Buffalo Agency in the twilight years of its existence in the 1930s. The chapter draws on a diverse body of materials including manuscripts from his private library, his research notes, and a recorded interview from the 1980s with him about his time in Cairo. He spent much of his life in the decades following his return from Egypt to Tunisia preparing materials for a book just like this one. Bin Yaʿqūb’s story is thus at once that of the gradual disintegration of the Agency and its library and the earliest attempt to preserve the memory of the Ibadi community in Cairo and the Buffalo Agency before it disappeared. Although he died before writing it, the idea for his book both inspired and laid the foundation for this one.
