Issue No. 04 - April (1975 vol. 24)
IN introducing what some may consider an unusual special issue, it is appropriate to recall that at the 1967 Fall Joint Computer Conference, the name of this journal was changed from IEEE TRANSACTIONS ON ELECTRONIC COMPUTERS to IEEE TRANSACTIONS ON COMPUTERS. This Special Issue on Optical Computing aptly reflects the broad aspects of computing for which this journal was intended.
