For better or for worse, Wikipedia has become the first destination for many a student researcher. Does the site’s ubiquity mean that professors have a responsibility to contribute? “I feel I have an obligation to do so, at least within my field,” said Alexander M.C. Halavais, an assistant professor of communications at Quinnipiac University, during a live Chronicle chat yesterday. “Public scholarship…is an important part of being a professor,” Mr. Halavais said. “Since Wikipedia is probably the single most visible source of knowledge for many today, it strikes me as an important place to engage in that role. I would love to see universities and tenure committees embrace that role, but I am not holding my breath.” A complete transcript of the chat — in which Mr. Halavais discussed Wikipedia’s strengths and weaknesses, and the role of the encyclopedia as a research tool — is now available online.
