In the years before the publication of this book, there had been a marked interest in the methodology of historical geography as well as in its underlying philosophies and analytical techniques. Originally published in 1982, this volume of essays comprises the revised version of most of the papers read and discussed during the symposium held in Cambridge in 1979, and sponsored the International Geographical Union's Working Group on Historical Changes in Spatial Organization. Some of the essays review developments within particular schools of historical geography, whilst others consider the difficulties of identifying and interpreting geographical change. These essays attempt to promote discussion about the purpose and practice of historical geography, and they will be of interest not only to geographers, but also to historians, historical sociologists, anthropologists and demographers, and to all concerned with the methodology of historical enquiry.
