This thesis is a case study analyzing the revisions made to three Wikipedia articles, 'The Hitchhiker's Guide to the Galaxy,' '2009 Northwestern Wildcats football team,' and 'Murder of Annie Le,' in September, 2009. After tracking and coding the revisions made to each of these three articles using categories developed by Sam Dragga and Gwendolyn Gong and Lester Faigley and Stephen Witte, I describe the types of changes made to Wikipedia articles, the differences in changes made to articles at different levels on Wikipedia's quality scale, and the features that make online editing distinct from print editing.
