CMR
Massachusetts state agencies issue regulations, which are compiled in the Code of Massachusetts Regulations (CMR). The CMR is updated by the Massachusetts Register on a bi-weekly basis, and we update this site on the same schedule.  For your convenience, we have also developed an index to the regulations, called CMR by Subject.
