The classification and distribution of the languages of the Northern Bantu Borderland between the Great Lakes and the Indian Ocean have been given in Volume 1 of where however, the linguistic evidence on which the classification rested was not included. This is now set out in this volume, originally published in 1957. The languages have been divided into three categories: Bantu, partly Bantu and non-Bantu. within each category the languages have been grouped according to linguistic criteria. The choice of languages represented here has been determined by the availability of reliable linguistic material.
