Last month over at the Volokh Conspiracy, guest blogger Ira Matetsky had an interesting series of posts about Wikipedia. Matetsky is a New York litigation attorney and a Wikipedia administrator and member of the in-house Arbitration Committee. In the posts he gives some inside insight into the workings of Wikipedia and discusses flaws and virtues of the site.
I would also recommend Diane Murley’s article In Defense of Wikipedia. It is written from the perspective of a law librarian and talks about the use of Wikipedia in legal research. While written to an audience of law librarians and legal research instructors, I think it provides some good information for all legal researchers.
