It has a lot of history that is relevant to, in many cases North America in general. It tells when & where the first appearances or introductions of the different species occurred, etc.
It isn't only Arthropods, but it does cover a spider and some arthropods. Because there is so little "new" info available for the Pacific Northwest, I wanted to include this in the Book list.
