The slogan of the Filled Pause Research Center (see header at top of this page) is "Investigating um and uh and other hesitation phenomena". In keeping with this slogan, the FPRC will maintain a bibliography of books, articles, conference presentations and papers, and other documents related to the study of disfluency. The goal is to add citation information, abstracts, and links to where users can download original documents in a database that is indexed and fully searchable. Of course, at first, I expect there will be a number of gaps, some which are perhaps sizable. Over time, though, I hope to close those gaps, perhaps with the kind and generous assistance of users of the bibliography. I doubt it will ever be fully comprehensive, but if the point can be reached wherein this is the go-to place to begin one's research in disfluency-related phenomena, then I will be quite satisfied.
