The state registrar may, where feasible, require permanent local records to be kept in the form of copies of the original vital statistics records. The state registrar shall designate in each case how this is to be done by the local recording official, in connection with other local registrars of vital statistics in the recording area. The state registrar shall issue instructions concerning the keeping of these records, their disclosure, corrections, issuance of copies, and fees to be charged. In matters pertaining to the system of vital statistics, the local recording officials and local registrars shall be directly supervised in this work by the state registrar.
