This series consists of files, known as 'volumes' containing reports, telexes, correspondence, etc. relating to the subject of the file. The files are ordinary manila file covers bearing the agency's name, the item number and title; item date range; disposal review date; and file movements. Files can contain material, inherited from predecessor agencies such as the Commonwealth Investigation Service and the wartime Security Service, which was considered of continuing value at the time of inheritance. Some items in the series have been microfilmed as a disposal measure prior to destruction. These items now form part of CRS A6126, Microfilm copies of personal and subject files (CRS A6119 and CRS A6122), c1960s- This material is retained by ASIO. Requests for access under s40 of the Archives Act 1983 are submitted to ASIO, who then undertake the research task of identifying if any records belonging to this or related series contain information relevant to the subject of the access request. Material is only transferred to Australian Archives as a result of these requests, and at the time of transfer a single number is imposed.
