Selection and destruction information: Between 1909 and the early 1970s many files were destroyed. In the late 1960s when destruction caused operational difficulties, the policy was changed to retain all records. To save space, older files were microfilmed and the originals destroyed. In the early 1990s, after Communism's collapse and the decline in threats from subversion, the review and destruction process was re-instated. In 1998 the Advisory Council on Public Records recommended changes to the Service's criteria for selection of records for permanent preservation; and in particular that a detailed operational selection policy should be developed within the PRO's acquisition policy programme (published as OSP 8 in 2001).
Accruals: Series is accruing.
