This disposal authority allows agencies to destroy a range of source records that are no longer needed once they have been copied, converted or migrated, provided equivalent reproductions are maintained and there are no special requirements to retain the source records. It also sets conditions for the proper management of copying, conversion and migration processes, the reproductions that are generated through those processes, and the source records themselves. The General Disposal Authority for source records both replaces and expands the coverage of GDA 22, which applied only to records of short-term value that had been copied.
