It is an annual campaign where librarians add references to improve Wikipedia, is coming back again this year, running from May 15th to June 5th, 2018. It is being run for the second time from this year because we heard from you a desire to run it again out of excitement. Librarians, community members, and affiliates are encouraged to make 1Lib1Ref [their own]. So whether we call this 1Lib1Ref May, 1Lib1Ref for the Southern Hemisphere, or 1Lib1Ref Strikes Back, the point is the excitement is building again, and we'd like you to be a part of it.
If you would like host a session at a local library, here are some materials for you:
"Imagine a World where Every Librarian Added One More Reference to Wikipedia" Wikipedia is a first stop for researchers. Let's make it better! Your goal today is to add one reference to Wikipedia! Any citation to a reliable source is a benefit to Wikipedia readers worldwide.
