The #1Lib1Ref campaign is now in its 9th year! Wikimedia Canada invites you to participate in the Canadian #1Lib1Ref competition running from January 15th to February 5th, 2026.

Wikipedia is the free encyclopedia that anyone can edit. To make sure that Wikipedia articles contain credible information, contributors have to include citations to reliable sources when they add new information. Many Wikipedia articles lack sources or have sources that ae outdated.

The goal of the #1Lib1Ref campaign is to encourage information professionals, like librarians, to contribute at least one reference to an article on Wikipedia to help improve Wikipedia’s reliability and verifiability.

Wikidata is another Wikimedia project that relies on references to ensure verifiability. Due to the popularity of adding references to Wikidata in 2025, we decided to make this a larger part of the #1Lib1Ref contest in 2026.
