ACM Classification Codes

The ACM Computing Classification System is a subject classification system for computer science devised by the Association for Computing Machinery. The system is comparable to the Mathematics Subject Classification in scope, aims and structure, being used by the various ACM journals to organize subjects by area. (Taken from Wikipedia.)
