There is no better compendium of studies at a time when the application of behavioral principles was on the threshold of defining a new discipline.  Chapters by Azrin, Ayllon, Goldiamond, Baer, Wolf, Risley, Lindsley, Patterson, Bijou and others who were the pioneers of applied behavior analysis.  Hardbound, good condition.  Listed for $63 on ebay....a steal here.
