The writings of Harold J. Noah and Max A. Eckstein are well known in the field of comparative education. For over three decades, they have worked and published collaboratively. Both separately and together, they have made major contributions to the field. This book brings together selections from their work, showing how their thinking, and that in the field as a whole, has evolved over the decades. The book makes available extracts from seminal works which had gone out of print, and places them between the covers of a single volume. The book commences with a foreword by Philip Foster, who is another distinguished figure in the field and who analyzes the work of Noah and Eckstien in its historical context. Foster notes that Noah and Eckstein write with 'Clarity, felicity, and economy'. From the earliest stages of their careers they have also written with penetrating insight. The Comparative Education Research Centre at the University of Hong Kong is proud to publish this collection, which will become a major reference work for new generations of scholars in the field of comparative education.
