Princeton NJ: Princeton University Press, (1998. reprint). Octavo, more than 357 colour plates, owner's sticker, a very good copy in dustwrapper.

The first identification guide to cover all the species to have occurred in the region, illustrating every one (including vagrants and accidentals). The species are organised by family, with each family introduction followed by the species accounts and relevant colour plates; text and plates are fully cross-referenced for easy use. Status and habitat are described in detail and the colour range maps provide clear distribution information.
