Review of the 4th Edition:
"Ian Mason, the author, has made a prodigious effort to keep this dictionary up-to-date in an era when synthetic breeds are appearing with great frequency...The publication is a useful reference for any veterinarian interested in the development and history of livestock breeds. It should also be in all reference libraries which aim to serve veterinary and livestock interests."
(W J Pryor, Australian Veterinary Journal)Review: 5th Edition
"Mason's offers well-organized, in-depth international coverage of livestock, identifying major breeds, listing existing and extinct breeds." S.J. Bryant, CHOICE, February, 2003
