TFH 1994 (English translation), Reprinted 1996
Although a bit out of date with names now, this book is well worth having for any Polypterus enthusiast. It contains some superb photographs and was the first hobbyist-orientated book with comprehensive information on Polypterus, as well as other primitive fishes. Contains several pages on raising Bichirs, as well as two sections on breeding Polypterus.

The Rise of Fishes - 500 million years of evolution
John A. Long
John Hopkins University Press 1995
Mainly for more general interest on the evolution of primitive fishes rather than for information on Polypteridae specifically, the book makes reference to the place of Polypteridae in the evolution of fishes. Oddly, it refers to "reedfish" as the common name for Polypterus species.
