Answer:

Our Society supplies information on our website and through our quarterly Journal. We do not have books for sale. :( The ones I recommend for reference are McCoy Pottery, Collectors Reference and Value Guide by Hanson/Nissen/Hanson (3 vol. set) and Sanfords Guide to McCoy Pottery by Steve and Martha Sanford. Although you might find them in book stores or antique stores book sections, they are all out of print. Ebay is a good source to find copies.
