#1Lib1Ref (known in some Romance languages as #1Bib1Ref) is a Wikipedia campaign inviting librarians to participate in the online encyclopedia project, specifically improving articles by adding citations.
The first #1Lib1Ref campaign coincided with the 15th anniversary of the founding of Wikipedia in January 2016.[1][2][3] Based on the premise of One Librarian, One Reference, organizers estimated that if each librarian on the planet spent 15 minutes adding a citation, the combined effort would eliminate English Wikipedia's backlog of 350,000 "citation needed" notices.[4] The inaugural, weeklong event ran from 15–23 January 2016, and employed the hashtag #1lib1ref on various social media platforms.[5]
