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.
