In addition to the acknowledgments cited in the previous prefaces, we wish to recognize some individuals directly related to this edition. We are indebted to Brian MacKay￾Lyons and to Thomas Phifer for each generously agreeing to provide us with information about two of their houses that had previously not been published so that we could include their work in this edition. At Brian Mackay-Lyons’ office, Lisa Morrison and Sawa Rostkowska were especially help￾ful. At Phifer’s office, Stephen Varady was similarly helpful. This edition would not have existed at all without the efforts of Margaret Cummins of John Wiley & Sons. As with the third edition, she approached us about considering a fourth edition. As previously stated, her powers of persua￾sions, her suggestions, and her encouragement were each critical to the development of this edition. We are profound￾ly grateful that she cares about this book and is willing to act on its, and thus our, behalf. The other members of the edito￾rial, art, and production staffs at Wiley were also helpful and deserve our thanks. It is impossible to adequately thank all the individuals who had an influence on this work, con￾tributed to its development, or encouraged us to continue pursuing the analysis of precedent and this book in particu￾lar. Look what you started, George E. Hartman, Jr., FAIA Emeritus, those many years ago. As with previous editions all of the pages in this edition are from original drawings. We have produced the analytic diagrams in freehand on tracing paper, thus we are responsi￾ble for their content. As was the case with the third edition, Jason Miller has interpreted our sketches and diagrams to precisely draw the twenty-eight new pages in this edition. We owe him a special thank you for his precision, dedica￾tion, diligence, patience, and great skill in producing the drawings; and for his sense of humor in dealing with us. Finally, over many years now our students, as well as those from other schools, have demonstrated that the study of precedents as presented herein is a valuable tool for design. They have challenged us and made each day we teach interesting through their questioning and discovery. Roger H. Clark Michael Pause June 2011 xi
