This week is Wikipedia’s 15th birthday and the Wikipedia Library has created the #1lib1ref campaign this week to encourage information professionals and others to add one citation to Wikipedia’s many  tags in their articles. If every librarian in the world added one citation, there would be no more  tags!
The Internet Archive is a great source for fact checking and our web-native content is easy to cite! Here’s some more information if you’d like to get started.
- There’s a Facebook group for the event if you’d like to ask questions or you can send messages to the Wikipedia Library on Twitter.
- This Citation Hunt tool can help you find articles needing cites.
- Not sure how to add a citation? Look at these citation templates. You can also read this help page about citing Internet Archive pages specifically (pdf tip sheet).
You can start from our texts collection, use our advanced search or try Open Library’s full text search. You can even add citations to content from our TV News Archive which can search captions or find historical information about the internet using the Wayback Machine. The campaign only goes through the 23rd but please feel free to keep adding citations and increasing the usefulness of Wikipedia by using our primary and secondary source materials.
