#1Lib1Ref (known in someRomance languages as#1Bib1Ref) is aWikipedia campaign invitinglibrarians to participate in theonline encyclopedia project, specifically improving articles by addingcitations.
The first #1Lib1Ref campaign coincided with the 15th anniversary of the founding of Wikipedia in January 2016.[1][2][3] Based on the premise ofOne 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 thehashtag#1lib1ref on varioussocial media platforms.[5]
The inaugural campaign ended with 1,232 revisions on 879 pages, by 327 users in 9 languages, using the hashtag #1lib1ref in the edit summary; these numbers likely underestimate the overall impact, since many participants were observed omitting the hashtag from edit summaries. OnTwitter the #1lib1ref hashtag was used in over 1,100 posts by over 630 users.[6]
The campaign has been revived as an annual celebration of Wikipedia's birthday,[7] expanding into a three-week event in subsequent years.[8] The 1Lib1Ref campaign is part of theWikimedia Foundation'sGLAM outreach strategy to involve librarians in the improvement of Wikipedia,[9] and other Wikimedia projects (as of 2022 plans).[10]
