Most area (formerly district) offices have a district book, a volume of typescripts on local history, customs, and administration. Some of these are of considerable importance. The Tanzania National Archives is microfilming them. Photostats of a few books are in the library of Makerere University College, and typescript selections may be found in the Tanzania National Museum, the School of Oriental and African Studies in the University of London, and Rhodes House, Oxford,
One or other copy of each book has been used in this study, with the exception of Chunya, Mpanda, and Nachingwea. The area offices do not possess German records.
