I would like another category for reference materials. Books like "The Birds of Texas", "Fish and Fishing in Iowa", "Wetland Plants and Plant Communities of Minnesota and Wisconsin", Inland Fishes of Mississippi" and other books like this are not widely known or available.
Also, there are organizations like "The Purple Martin Ass.", "N.A. Bluebird Soc." and "Bat Conservation Int." that people might be interested in. It took me forever to find prefab wood duck houses.
