This is one of the most useful books I have ever read and I am very pleased to see it republished in this form.
I would be even more delighted to see "Mechanisms of Intelligence: Ashby's Writings on Cybernetics", a rich collection of his (mostly) later and more advanced work edited by Roger Conant, republished in this form too. It was published by Intersystems publications in 1981 and, as far as I can tell, has never been reprinted. I am sure there are many people besides myself who would like to be able to get hold of a copy.
Republication of "Design for a Brain" would, of course, complete the set. :-)
