The Orb-weaving Spiders of Canada and Alaska - The Insects and Arachnids of Canada Part 23
By Dondale, C.D., J.H. Redner, P, Paquin and H.W. Levi
NRC Research Press, 2003
After being discontinued for 10 years, monographs are again being published in the excellent Insect and Arachnids of Canada series. This is the first of, hopefully, more to come. I'm sorry it took me 2 years to find out about this exciting development.

Can be ordered directly from the web starting at:
or start at: and see what else you can get.

As for the book itself it covers spiders of the Uloboridae, Tetragnathidae, Araneidae, and Theridiosomatidae and seems to be good for Canada and the northern USA. Their dot maps cover all of Canada and the continental USA and despite the title, just flipping through I don't see many that actually make it to Alaska. Indeed many of the species covered don't even come into Canada. Perhaps they are expected. I have not read the introduction extensively yet.
