The Division of Veterans' Services of the Department of Economic Development shall distribute the registration records, formerly maintained by the State service officer, of veterans' graves in each county to the supervisor of veterans' interment in each county. Such records shall be maintained by such supervisor of veterans' interment in a suitable place therefore designated by the board of chosen freeholders by such county.
Each of such supervisor of veterans' interment is hereby charged with the duty of keeping the same up-to-date; of assembling, recording, checking, correcting and filing any and all records, charts or maps concerning the location within his county of the places of burial of veterans of all wars; and of using such forms therefore as the Department of Economic Development may prescribe; to the end that there shall be a complete and uniform record of all graves in New Jersey in which veterans are buried and that such records shall always be kept up-to-date.
