The Wikipedia #1Lib1Ref campaign starts soon! "Your goal today is to add one reference to #Wikipedia! Any citation to a reliable source is a benefit to Wikipedia readers worldwide." Make sure to include the hashtag #1Lib1Ref in your edit summary. 1lib1ref.org
Last year was my first year participating in #1Lib1Ref and I am thoroughly hooked! Trying to make it a regular part of my praxis to add relevant citations to #Wikipedia when I’m doing collection development or answering reference questions.
