In the Summer of 1979 the members met again for the 4th International Congress of ISEK, this time in Boston (August 5-10, 1979). The secretary general of the meeting was C.J. De Luca. A book containing the proceedings of that meeting was published. The ISEK logo was improved and refined and appeared on all the Congress literature. It is the logo that appears on all of the ISEK literature now.
