§ 57.29. Reproduction of records and disposition of the originals. Any local officer may reproduce any record in his custody by microphotography or other means that accurately and completely reproduces all the information in the record. Such official may then dispose of the original record even though it has not met the prescribed minimum legal retention period, provided that the process for reproduction and the provisions made for preserving and examining the copy meet requirements established by the commissioner of education. Such copy shall be deemed to be an original record for all purposes, including introduction as evidence in proceedings before all courts and administrative agencies.
