Blench, Roger. Archaeology, Language, and the African Past. (African Archaeology Series, vol. 10. Lanham, MD: AltaMira Press. 2006. Pp. xxv, 361. ISBN 0-7591-0446-2. Paperback. $44.95.

"Contested methodologies" [33-87] focuses on disputes over the scientific validity of methods in historical linguistics, problems with focusing on written languages, and introduces glottochronology, lexicostatistics, historical reconstruction, methods of language classification, and the impact of language contact and shift for historical research.
Chapters on language phyla follow. "Nilo-Saharan" [95-108] presents Nilo-Saharan, its internal grouping, previous research on reconstruction, the age of the phylum, how it expanded, and the problem that many major subgroups tend to be single languages.
