Editor´s notice [Change of Associate Editor]

Prof. Robert Minnick has asked to be relieved of the Associate Editorship for Logic and Switching Theory. At Bob´s suggestion and the concurrence of the Publications Committee, the Associate Editorship for Logic and Switching Theory has been split into two parts: Switching Theory and Logical Design. I am happy to announce that Warren Semon has agreed to become Associate Editor for Switching Theory, and that Paul Morton, who has been Associate Editor at-large since February 1966, has agreed to assume the duties of Associate Editor for Logical Design. Warren´s biography follows and Paul´s biography was published in the February 1966 TRANSACTIONS.
