"Mark Harvey has once again produced a volume that will be enormously useful to arachnologists around the world. The arachnid orders covered by this catalog loom large in all attempts to deal with biodiversity, and include some of the most interesting of all arthropods. This volume provides an easy and authoritative portal into the existing knowledge of these fascinating creatures."
". . . it is an essential addition to the library of all arachnologists. It will also be invaluable to those involved in biodiversity studies worldwide by clarifying the current taxonomic position of these important arthropod taxa and providing a reliable bibliographic resource."
