Wikipedia is a free online encyclopedia that is written and edited solely by volunteers who have no qualifying credentials save an internet connection. With over 3.1 million articles in English, Wikipedia is indeed a formidable reference web site. From a research standpoint, Wikipedia is both the sinner and the saint: because anyone can make changes to content, Wikipedia lacks scholarly backbone in the form of subject experts and a referee process, but there is strength in its continual updating, allowing new information to be added very quickly instead of taking years to be added to a traditional print encyclopedia. While it certainly should not be the one and only source for undergraduate research, Wikipedia may have appropriate uses in the college classroom. This article describes how two faculty at Lycoming College incorporated this resource into a research and information literacy project, with the goal of enhancing students' critical awareness of its strengths and limitations.
