With many excellent books on medieval stained glass available, the reader of this anthology may well ask: "what is the contribution of this collection?" In this book, we have chosen to step away from national, chronological, and regional models. Instead, we started with scholars doing interesting work in stained glass, and called upon colleagues to contribute studies that represent the diversity of approaches to the medium, as well as up-to-date bibliographies for work in the field. Contributors are: Wojciech Balus, Karine Boulanger, Sarah Brown, Elizabeth Carson Pastan, Madeline H. Caviness, Michael W. Cothren, Francesca Dell'Acqua, Uwe Gast, Francoise Gatouillat, Anne Granboulan, Anne F. Harris, Christine Hediger, Michel Herold, Timothy B. Husband, Alyce A. Jordan, Herbert L. Kessler, David King, Brigitte Kurmann-Schwarz, Claudine Lautier, Ashley J. Laverock, Meredith P. Lillich, Isabelle Pallot-Frossard, Hartmut Scholz, Mary B. Shepard, Ellen M. Shortell, Nancy M. Thompson.
