SIGS - SPECIAL INTEREST GROUPS

ACM's Special Interest Groups (SIGs), devoted to the
technical activities of its members, offer the individual ACM member all
the advantages of a homogeneous, narrower-purpose group within a large
professional society. The SIGs operate as semiautonomous bodies within ACM
for the advancement of activities in varying subject areas. ACM members are
eligible to join as many special interest groups as they wish.

    The most common activites of each SIG include: publishing a newsletter
(which is one of the membership benefits, see page     for information on
ordering) organizing technical symposia and workshops (registration fees and 
proceedings are discounted for SIG members), and sponsoring technical sessions 
at computer conferences.

    These are numerous overlaps in specified subject areas of the existing SIGs.This has occurred because the information processing field is still growing 
rapidly, and the importance of, and approach to, various subjects keeps 
changing. As these changes influence the activity of a SIG, the need for 
another group arises and a new SIG is formed.
