Each of the contributions to this volume may be taken as a complete, freestanding discussion. Each is printed with its own end notes (if any are used), but the reference lists are compiled into one single alphabetical list at the end of the volume. This compilation of references is provided in part to eliminate duplication, but in part also to give a sense of the scope of the field, of the key players, and of the disciplinary history. There is also an index at the end of the volume, as well as a brief biographical listing of the contributors. The biographic entries were written by the contributors. Each entry provides an e-mail address at which the author can be contacted. Aside from these features, the approach is intentionally conservative, offering no special features and deliberately avoiding cross-reference among the contributions. Readers are invited to contact the editor or the members of the editorial with questions or comments.
