The Epistemology of Wikipedia

Yes, another Wikipedia article. But Wikipedia really is the elephant in the room for any discussion of online information, and this essay is a useful addition to the dialogue.
The author, a computer scientist, provides a very even-handed discussion of what constitutes and defines "truth" and knowledge in the Wiki world. There is something here for both critics and advocates of the the Wikipedia phenomenon.

Librarians as Wikipedia Contributers

This article proposes librarians as natural contributors to Wikipedia. The emphasis is on university librarians and how they can use Wikipedia to highlight their special collections. This has limited applicability to school libraries, but the article includes an excellent summary of Wikipedias "rules and culture" for potential editors and contributors.

Wikipedia, the Good

Controversial though it is, Wikipedia has some undeniably excellent attributes. One of these is as a news aggregator for fast breaking current events. See this article from the New York Times outlining how it rapidly and reliably pulls together many strands of a complex story.
