No one is upset. The APA has no control over what is dedicated to them. The APA does not endorse any of these books as being accurate. They may be accurate, but the APA has nothing to do with any of these publications. The APA Standard is the proper place to look for visual descriptions, as the illustrations follow the written shape for the breed. Schillings illustrations are accurate, but many of the other drawings and pics depict a bird that does not agree with the current APA descriptions. I like the old works, but just because they are old does not mean they are accurate/true.
