Excerpt from Robert Curthose: Duke of Normandy It is more than a pleasure to acknowledge my Obligations to those whose counsel and assistance have been constantly at my disposal in the preparation Of this volume. By the librarians and their staffs in the libraries of Harvard University, the University of California, the University Of Pennsylvania, and Bryn Mawr College I have been treated with a courtesy and helpfulness which are beyond praise. Mr. George W. Robinson, Secretary Of the Graduate School of Arts and Sciences Of Harvard University, has given me much valuable assistance in preparing the manuscript for the press and in the correction Of the proof. Finally, I have to acknowledge a debt Of gratitude which is deeper than can well be expressed in writing, that which I owe to my teachers. It was Professor Dana C. Munro, now Of Princeton University, who first taught me to care greatly for the Middle Ages and awakened my interest in the Crusades. He has followed this volume with kindly interest while it has been in the making, and has given me much helpful criticism upon that part which relates to the First Crusade. But above all I am indebted to Professor Charles H. Haskins Of Harvard University, at whose suggestion this work was first undertaken and without whose help and counsel it could hardly have been brought to completion. While the author must accept full responsibility for the statements and conclusions herein contained, it is proper to say that the documentary ma terials which Professor Haskins had collected, as well as the results Of his own researches, were placed at my disposal in manu script before their publication in his recent volume entitled N ormc nstitutions, that separate chapters as they have been prepared have passed through his hands for detailed criticism, and that his unfailing patience has extended even to the reading Of the proof sheets.
