This script runs when you search RecordSearch (the National Archives of Australia's database) for ASIO files in the Series A6119. It retrieves information from a database of redactions that I've extracted from the files and inserts it in the RecordSearch description.

See installing userscripts in my Digital Heritage Handbook for information on installing this script.
