In 2004, the State Records Office released its first online catalogue to the State archives collection: AEON - Archives Explored Online. In 2015, AEON was replaced by a new online catalogue: AtoM - Access to Memory.
Please note that the AEON catalogue will be fully decommissioned on 10 February 2018 and will no longer be available. If you have bookmarked links to AEON, it is recommended you update these to point the new AtoM catalogue.
Further information on using AtoM is available at: http://www.sro.wa.gov.au/archive-collection/searching-our-new-database-system.
