This case study describes the process of proposing and implementing a wiki for use in an academic library setting, based on the process used by Iowa State University Library. Using the Iowa State University Library Wiki as a model, this article lays out the decisions necessary at each step of the process of establishing a new wiki. Control of potentially sensitive data and other security concerns led the Iowa State University Library to implement a PmWiki installation on its own server. This article provides helpful advice for any librarian who is thinking about implementing a wiki but unsure of where to start. As librarians everywhere discuss the potential of wikis and their potential pitfalls, this article offers an example of a successful project with an eye on what might have made it successful.
