The Scientists' Committee on Loyalty Problems, formed by the Federation of American Scientists in the fall of 1948, has been succeeded by the Scientists' Committee on Loyalty and Security, centered in New Haven, Connecticut. Concerned “with security programs as they affect individual scientists, leaving to other groups the study of such programs with respect to civil liberties and democratic processes”, the Committee is maintaining a file of up‐to‐date information on loyalty and security regulations and slates that this information and informal advice is available to interested scientists on request, but that “the Committee does not attempt under any circumstances to judge the merits of individual cases”.
