Acknowledgments
These papers grew out of a series of special sessions of the annual meeting of the Association of American Geographers in 2003. We thank all who participated for their role in fostering conversation about the intersections of geography and citizenship. In addition, we would like to thank the anonymous reviewers of the papers gathered here for their gracious and insightful comments on multiple drafts. The authors each benefited tremendously from the reviewers' time and attention to their work.
