Redactions extracted from ASIO surveillance records in National Archives of Australia Series A6119
This is a collection of 239,571 redactions (blacked out words and phrases) extracted from surveillance files created by the Australian Security Intelligence Organisation (ASIO) and held in Series A6119 at the National Archives of Australia.
The digitised records were harvested from the NAA's online database as a collection of individual page images. These images were then processed to find and extract redactions.
The script used to extract the redactions is in the linked GitHub repository. After running the script, I manually removed non-redactions (these are available in a separate fileset for comparison). There was about a 20% error rate.
The redactions are saved as jpgs and are mostly very small images. The filenames of the images provide important contextual information. For example:
1009279-p10-1-74-54.jpg -- has the following attributes
File barcode: 1009279
Redaction number: 1
You can search the NAA database to find the original file using the barcode, or construct a link like:
