Permission
(Reusing this file)		 A search was made from the copyright renewals in 1972[1][2] and the first half of 1973[3] (but admittedly not the second half of 1973[4] because it is not organized in an easily searchable manner) under the titles "A.P.A", "American Psychological Association", "APA", "Duncker", "On Problem Solving", and "Psychological Monographs" - no entries were found. This book appears not to have renewed its copyright.
