Field Guide to the Spiders of California and the Pacific Coast States (California Natural History Guides)
By Richard J. Adams (Author) , Timothy D. Manolis (Illustrator)
University of California Press, 2014
With over 40,000 described species, spiders have adapted to nearly every terrestrial environment across the globe. Over half of the world’s spider families live within the three contiguous Pacific Coast states—not surprising considering the wide variety of habitats, from mountain meadows and desert dunes to redwood forests and massive urban centers. This beautifully illustrated, accessible guide covers all of the families and many of the genera found along the Pacific Coast, including introduced species and common garden spiders. The author provides readers with tools for identifying many of the region’s spiders to family, and when possible, genus and species. He discusses taxonomy, distribution, and natural history as well as what is known of the habits of the spiders, the characters of families, and references to taxonomic revisions of the pertinent genera. Full-color plates for each family bring to life the incredible diversity of this ancient arachnid order.

Collins Field Guide: Spiders of Britain & Northern Europe
By Michael J. Roberts
Harper Collins, London, 383 pp., 1996
This is actually Roberts 1995 in the World Spider Catalog. The year might have been a typo?

This is a great book to have; 450 species are covered, each with genitalia illustrations, and 288 of them include a color painting. We have lots of European imports here and they can usually be found in this book.
