Ekoid Bantu Languages of Ogoja, Eastern Nigeria, Part 1, Introduction, Phonology and Comparative Vocabulary  (English, Paperback, Crabb David W.)

Dr Crabb's 1965 study of the Ekoid Bantu languages of Ogoja examines these related languages as a basis of comparative historical research. He chose fourteen of these Ekoid languages as representative of a number of languages in the north-west area of Nigeria bordering on the Bantu language area, whose status as Bantu languages has been open to question. This study is based on extensive field work and presents comparatively the phonologies and selected vocabularies of the languages.
