Spiders of California: Hosted by Steve Lew (last updated in 2004). From the website, “In 1979 Steve Johnson made a list of all spiders known from California. He had essentially unlimited literature resources as a graduate student of B. J. Kaston, and also benefited from the expert assistance of Wendell Icenogle. I began this website by digitizing his list as reformatted by Donald Boe in 1989, with lab support form Rosemary Gillespie and coding assistance from Chris Seidel. As time permits I update the list using more recent publications and personal communication from skilled collectors known to me.”
