As Wikipedia has become more and more popular with students, some professors have become increasingly concerned about the online, reader-produced encyclopedia.

While plenty of professors have complained about the lack of accuracy or completeness of entries, and some have discouraged or tried to bar students from using it, the history department at Middlebury College is trying to take a stronger, collective stand. It voted this month to bar students from citing the Web site as a source in papers or other academic work. All faculty members will be telling students about the policy and explaining why material on Wikipedia -- while convenient -- may not be trustworthy.

"As educators, we are in the business of reducing the dissemination of misinformation," said Don Wyatt, chair of the department. "Even though Wikipedia may have some value, particularly from the value of leading students to citable sources, it is not itself an appropriate source for citation," he said.

The department made what Wyatt termed a consensus decision on the issue after discussing problems professors were seeing as students cited incorrect information from Wikipedia in papers and on tests. In one instance, Wyatt said, a professor noticed several students offering the same incorrect information, from Wikipedia.

There was some discussion in the department of trying to ban students from using Wikipedia, but Wyatt said that didn't seem appropriate. Many Wikipedia entries have good bibliographies, Wyatt said. And any absolute ban would just be ignored. "There's the issue of freedom of access," he said. "And I'm not in the business of promulgating unenforceable edicts."

Wyatt said that the department did not specify punishments for citing Wikipedia, and that the primary purpose of the policy was to educate, not to be punitive. He said he doubted that a paper would be rejected for having a single Wikipedia footnote, but that students would be told that they shouldn't do so, and that multiple violations would result in reduced grades or even a failure. "The important point that we wish to communicate to all students taking courses and submitting work in our department in the future is that they cite Wikipedia at their peril," he said.

He stressed that the objection of the department to Wikipedia wasn't its online nature, but its unedited nature, and he said students need to be taught to go for quality information, not just convenience.

The frustrations of Middlebury faculty members are by no means unique. Last year, Alan Liu, a professor of English at the University of California at Santa Barbara, adopted a policy that Wikipedia "is not appropriate as the primary or sole reference for anything that is central to an argument, complex, or controversial." Liu said that it was too early to tell what impact his policy is having. In explaining his rationale -- which he shared with an e-mail list -- he wrote that he had "just read a paper about the relation between structuralism, deconstruction, and postmodernism in which every reference was to the Wikipedia articles on those topics with no awareness that there was any need to read a primary work or even a critical work."

Wikipedia officials agree -- in part -- with Middlebury's history department. "That's a sensible policy," Sandra Ordonez, a spokeswoman, said in an e-mail interview. "Wikipedia is the ideal place to start your research and get a global picture of a topic, however, it is not an authoritative source. In fact, we recommend that students check the facts they find in Wikipedia against other sources. Additionally, it is generally good research practice to cite an original source when writing a paper, or completing an exam. It's usually not advisable, particularly at the university level, to cite an encyclopedia."

Ordonez acknowledged that, given the collaborative nature of Wikipedia writing and editing, "there is no guarantee an article is 100 percent correct," but she said that the site is shifting its focus from growth to improving quality, and that the site is a great resource for students. "Most articles are continually being edited and improved upon, and most contributors are real lovers of knowledge who have a real desire to improve the quality of a particular article," she said.

Experts on digital media said that the Middlebury history professors' reaction was understandable and reflects growing concern among faculty members about the accuracy of what students find online. But some worry that bans on citing Wikipedia may not deal with the underlying issues.

Roy Rosenzweig, director of the Center for History and New Media at George Mason University, did an analysis of the accuracy of Wikipedia for The Journal of American History, and he found that in many entries, Wikipedia was as accurate or more accurate than more traditional encyclopedias. He said that the quality of material was inconsistent, and that biographical entries were generally well done, while more thematic entries were much less so. Like Ordonez, he said the real problem is one of college students using encyclopedias when they should be using more advanced sources.

"College students shouldn't be citing encyclopedias in their papers," he said. "That's not what college is about. They either should be using primary sources or serious secondary sources."

In the world of college librarians, a major topic of late has been how to guide students in the right direction for research, when Wikipedia and similar sources are so easy. Some of those who have been involved in these discussions said that the Middlebury history department's action pointed to the need for more outreach to students.

Lisa Hinchliffe, head of the undergraduate library and coordinator of information literacy at the University of Illinois at Urbana-Champaign, said that earlier generations of students were in fact taught when it was appropriate (or not) to consult an encyclopedia and why for many a paper they would never even cite a popular magazine or non-scholarly work. "But it was a relatively constrained landscape," and students didn't have easy access to anything equivalent to Wikipedia, she said. "It's not that students are being lazy today. It's a much more complex environment."

When she has taught, and spotted footnotes to sources that aren't appropriate, she's considered that "a teachable moment," Hinchliffe said. She said that she would be interested to see how Middlebury professors react when they get the first violations of their policy, and said she thought there could be positive discussions about why sources are or aren't good ones. That kind of teaching, she said, is important "and can be challenging."

Steven Bell, associate librarian for research and instructional services at Temple University, said of the Middlebury approach: "I applaud the effort for wanting to direct students to good quality resources," but he said he would go about it in a different way.

"I understand what their concerns are. There's no question that [on Wikipedia and similar sites] some things are great and some things are questionable. Some of the pages could be by eighth graders," he said. "But to simply say 'don't use that one' might take students in the wrong direction from the perspective of information literacy."

Students face "an ocean of information" today, much of it of poor quality, so a better approach would be to teach students how to "triangulate" a source like Wikipedia, so they could use other sources to tell whether a given entry could be trusted. "I think our goal should be to equip students with the critical thinking skills to judge."
