Last week it was widely reported that editors at the prestigious science journal Nature released findings of an investigation they conducted regarding the accuracy of science articles published in the renowned Encyclopedia Britannica vs the upstart, free Wikipedia encyclopedia. In case you haven’t heard about Wikipedia (http://en.wikipedia.org) yet, it is a rapidly growing (nearly 900,000 articles in English since it began operations in January 2001) encyclopedia resource that anyone — that’s you and me — can edit. Of course, anyone who ever wrote a paper in high school has heard of the Encyclopedia Britannica. Britannica is the probably the most respected and widely known general purpose encyclopedia in the world.

Encyclopedia Britannica’s articles are written by highly credentialed scholars and thoroughly vetted by expert reviewers who are specialists in their field. Wikipedia’s strength (and weakness) is that anyone — layperson or expert — can contribute to existing articles. Articles in Wikipedia are reviewed by members of a community of 10,000 or so volunteer editors. Wikipedia received some bitter criticism recently from a famous journalist, John Seigenthaler Sr., who discovered an article about him which included outrageous, false information that someone had written as a prank. Following this unfortunate event Wikipedia now requires contributors to register before they can create new entries in the encyclopedia. However, anyone can still edit existing articles.
For their investigation the Nature editors chose a sample of 50 science related articles of comparable length from both encyclopedias. They submitted these articles for peer review by scientists who checked them for content accuracy. The results were rather astounding. Nature found that both encyclopedias commonly had inaccurate information in their articles. Even more astounding is that, overall, articles for Wikipedia had only slightly more errors than those in Britannica. The Nature editors concluded that Britannica and Wikipedia — at least so far as scientific articles are concerned — are equally reliable sources of information. The Nature editors went on to challenge the scientific community to become more widely involved in contributing new and editing existing science related articles at Wikipedia to make this great tool even better.
Wikipedia has caused uneasiness among some librarians and other educators. After all, our job has always been to recommend reliable and authoritative sources of information. Wikipdedia’s open content approach to building articles at first glance appears to turn the notion of authority on its head. Of course the revelation about the numerous errors in Britannica challenges authority as well.
Encyclopedias provide a great way to jumpstart many research projects. They provide concise, well ordered information on a subject and often include a bibliography and other links to more detailed information in books, journals, and other sources. Students who use Wikipedia for their research should do so with the understanding that it is an imperfect tool. Always check with your professor in advance for guidance on what tools she deems appropriate for your research. There’s a treasure of information resources for you to use through our website. As a researcher, you’re a fact checker. Check your facts. Never rely just on a single source.
