The article presents information on Association for Computing Machinery's (ACM) Special Interest Groups (SIG) and Special Interest Committees (SIC). The SIG on automata and computability theory addresses the theoretical and formal aspects of computing such as theory of automata, computational complexity and information structures. Methods used in the analysis, design, maintenance, and use of computer-based information systems are covered by the SIG on business data processing. ACM has several objectives in approving SIC on computers and the physically handicapped in August 1970 including the promotion of professional interests among computing professionals with physical disabilities.
