Wikipedia is a first stop for researchers and students. Libraries can help to make it a better resource!
University of New Hampshire Library facilitates a number of editor trainings and editing sessions throughout each year.
For example, in January and May we participate with library staff and librarians worldwide in 1Lib1Ref!, whose goal is for every participant to add a single reference to Wikipedia during the campaign period.
You can get a start on editing Wikipedia on your own. You'll find lots of starter tips here.
