 Quick Facts for Institutions

        • In 2021, Archeion pages were visited over 433,000 times by over 92,000 users; over 91,000 of those users were new visitors to the database.
        • While Canadians were heavily represented in Archeion users, thousands of visitors reached members’ pages from the United States in 2021, while hundreds more visitors connected from Asia, Australia, Europe… and the list goes on.
        • Archeion listings are indexed by Google, so member institutions’ contributions appear in regular Google searches. Adding your records to Archeion reduces institutional barriers to access and increases the discovery of your records.
        • The wide variety of subject, place and genre access points, as well as the shared list of authority records, allows users to discover your institution’s records from related records held by other institutions.
        • The Archeion Coordinator can train you to prepare bulk uploads of archival descriptions. Many institutions with existing databases or finding aids are able to map their data to the Archeion framework to simplify bulk uploading. The Archeion Coordinator takes care of uploads for Institutional Members.
        • Artefactual Systems Inc., our software host, performs nightly backups of Archeion data. All Archeion data is stored in data centres dispersed across Canada to ensure data redundancy and security, and to mitigate environmental risks.


Archival descriptions provide information about groupings of archival materials held by collecting institutions such as archives, museums, libraries and historical societies. These descriptions provide information about the archival records such as titles, dates, subjects, creators, and much more. You can explore our archival descriptions here.

Authority records provide information about the creators of the archival records described in Archeion. Creators may be individuals, families, or corporate bodies. Corporate bodies include businesses, institutions, governing bodies, social organizations, and any other group that creates and keeps records as a collective. The authority records in Archeion provide information such as the dates of existence of these record creators, their official names and other names, and their biographies or administrative histories. You can browse our authority records (referred to as “People and organizations”) here.

Institutional profiles in Archeion provide information about the AAO institutional members contributing archival descriptions and authority records to the database. These institutional profiles include contact information, as well as business hours, collections mandates and policies, institutional histories and more. You can visit Archeion’s institutional profiles here.
