The Massachusetts Criminal History and Your Own Copy
Massachusetts is one of the states that lets anyone look up another person's statewide criminal history: open access iCORI lets anyone request limited conviction information by name, for $25 a search, through the Department of Criminal Justice Information Services. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it. The search is on the Department of Criminal Justice Information Services site.
To see your own record, the route is a personal CORI request, free once a year online. The state page SearchSystems verified for it is at mass.gov/massachusetts-criminal-offender-record-information-cori.
