Walkers is Black and White photographs, many of them old photos, or of museum specimens or captive individuals.
HMW uses colour plates to illustrate the individual species and subspecies, and has chapters on families, behaviours etc, which is lavishly illustrated with some of the best wildlife photography you will see anywhere. There is much more text than Walker's too.
Walker's has been pretty much the standard mammalian reference work for all mammals, but HMW is going to surpass it.

I found out about Walker's in the 1970s, when I visited the Mammal Library in the Natural History Museum to do some work on the Octodontidae. I liked the way that Ernest P. Walker had tried to get at least one picture of a representative of each genus. Over the years, there are few genera that were not represnted by pictures. If you're a mammal geek, try Mammal Planet (
Welcome to Mammals' Planet | Mammals'Planet) for pictures of many mammal species. I have got each of the 6 editions of Walker's Mammals of the World. The last one was published in 1999, but has been superceded by paperback versions of various groups of mammals e.g. marsupials, carnivores, primates and bats. One of the things I like about Walker's is that it is not afraid to devote a lot of space to rodents and bats. Later editions have detailed accounts of species of cats and some other more familiar species, but there is still much space devoted to obscure genera of species.
I also have copies of various editions of David Macdonald's Encyclopaedia of Mammals, but I find it very lopsided. In the first edition, the first volume dealt mainly with carnivores, primates and whales and everything else was crammed into the second volume.
The Handbook of Birds of the World has been fairer as it has given a lot of space to each bird family. The Handbook of Mammals of the World seems to have fallen into a similar trap to the Encyclopaedia of Mammals. The popular mammals are getting a lot of space. One book for carnivores, one for hoofed mammals, one for primates and one for sea mammals. I'm pleased that the marsupials are getting a volume, but I wonder how much space some of the other mammals will get. I imagine that several pages will be devoted to beavers and some of the other popular species of rodents, but that some species will be represented by little more than a small sketch, a limited description, a few measurements and the countries where they live. I hope I'm wrong about this.
As some other Zoochatters have said, the structure of the volumes is already outdated. The pinnipeds should, and could, have been included in the carnivore volume, possibly along with the pangolins. Likewise, the whales should have been included with the hoofed mammals. The aardvark, elephants and hyraxes (Hoofed Mammals) and sirenians (Sea Mammals) should be in the same volume along with tenrecs, golden moles, elephant shrews and xenarthrans, which I can only guess will be in Volume 7. I don't think it can be that difficult to change the contents of some volumes, especially as the basic change in classification predates the publication of Volume 1. As there are relatively few species of pinnipeds, it wouldn't have been difficult to add them to Volume 1. Similarly Volume 2 could have included the whales or the volume on primates could have preceded the volume on hoofed mammals. I just hope that marsupials are classified in several orders, rather than just dumping them in the Marsupialia, which was one of the let downs of the Dorling Kindersley Handbook on Mammals
