History of the MRB
•Before 1967, there was no provision for eliminating obsolete local records
•
•Chapter 105 (1967) created RSA 33-A which created a list with 44 schedules. It also allowed  towns to adopt a local records committee to oversee records management. Microfilming was encouraged for several types of records.
–Chapter 231 (1969) added 2 categories of licenses to list of schedules
–
•Chapter 358 (1977) removed the schedules from the body of the statutes, and created a state Municipal Records Board to adopt administrative rules. The last iteration of the schedules by the Board were the Rules of 1995 which had 105 records types listed.
•
• Chapter 187 (2005) reinserted the schedules into the statutes; made the MRB advisory to the Secretary of State; and made a preliminary stab at electronic records. The statute now contains 153 records types.
