Spiders of Texas
"Gertsch & Mulaik started a list of Texas spiders in 1940. In a letter from Gertsch dated October 20, 1982, he stated “Years ago a first listing of the Texas fauna was published by me based largely on Stanley Mulaik material, but it had to be abandoned because of other tasks.” Vogel (1970b) published the Bibliography of Texas Spiders and recorded 560 species. This catalog is an update of Vogel’s list."

"This list contains 1000 species in 52 families. Many more species remain to be discovered."

Spiders of California
This is an authoritative checklist that aims (pretty much successfully) to list every species of spider ever recorded from California, along with synonyms, range (given in terms of counties) and citations of references in the taxonomic literature. It won't tell you how to identify any spiders, nor will it tell you anything beyond classification and range of species- but it will tell you the names and synonyms of species in a given county so you can look them up elsewhere.

Visually Identifiable Spiders
A handy list of spiders that can be recognized by their appearance alone. The brevity of the list should also serve as a warning that often we just can't be sure without having an expert look at a specimen.
