This is a reference work, not an easy read. It summarises knowledge of each species found in these islands (Ireland, Man, Channel Isles as well as GB), and cites the literature needed to supply this information. The authors (118 of them) are all experts on their species. Good quality paper allows full colour presentation of plates and photographs; skulls and teeth are depicted in monochrome. Three introductory chapters discuss the balance of the mammal fauna, its fossil history, and the relevant laws covering wild mammals, but most of the book (740 of 800 pages) is devoted to the systematic accounts. A bit pricy, perhaps, but very good value for money.
