Walker's Mammals of the World: Vol 1-2 - Tapa dura

"Professional naturalists will find [these volumes] invaluable as a handy reference, and amateurs -- at least those citizens alive to their earthly environment -- should delight in finding so much fascinating information made so available and palatable." -- Audubon.

"What an amazing lot mammals are, seen here in all of their diversity!... Walker has made available a mine of information, for the specialist as well as for the casually interested... If you want to find out about a mammal, then, here is the place to look." -- New York Times

"Every mammalogist must have [these books], and those who profess a broad interest in the fauna of the world will want them." -- Natural History

"Speaking as a reader who is mildly addicted to 'standard works of reference', I must say that I find it a very welcome addition to my library, and suspect that it will become my regular first port of call when trying to answer any mammalogical question." -- Nicholas Gould, International Zoo News

"An absolute treasure trove -- a `must' for the working naturalist as well as for any person who has curiosity about the world's mammals." -- Roger Tory Peterson.
