About this plate
THE MASSACHUSETTS SPECIALTY INDEX, a count, its date, and its staleness, which is the honest shape when the live catalogue will not serve. Worth carrying forward: unlike Connecticut, where the legislature authorises each program and the count is therefore statute-derivable, Massachusetts creates most programs administratively and only occasionally by statute (Cape and Islands), so the count can only ever come from an RMV artefact. That makes the RMV booklet worth capturing on a schedule, for the same reason Florida's monthly active-plate report is: it is the only structured record, and its publisher does not archive it.
