Preservation is a core function of any record office. It is central to a record office’s role as guardians of archival heritage. Preservation helps to ensure that all of us have an equal opportunity to see and enjoy unique and important records. The formulation of a preservation policy for PRONI is, therefore, an essential step in fulfilling all these responsibilities and gives PRONI the direction it requires to initiate measures which are necessary for the protection of its archives. The policy also enables staff to meet, or extend, nationally and internationally agreed standards for the preservation of archival materials to ensure that records are to saved for present and future generations.
