The ISSS logo, derived from the integral sign originally used by the founders of our society, illustrates the society's primary interest in integration and synthesis and can be used to demonstrate these principles. The first online version of the logo, adopted by ISSS in 1997, was designed by Thomas M. Mandel, the founding webmaster of ISSS.org. The current version, updated in 2017, reverts to an earlier design and color used on the covers of Yearbooks
