More Information

  • 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.
