This collection of papers is a result of an academic conference entitled ""Books in Numbers"" held in celebration of the seventy-fifth anniversary of the Harvard-Yenching Library. The aim of this conference was to celebrate the book culture of East Asia by comparing and contrasting the development of manuscript and print culture in each of the separate cultural areas of the region: China, Korea, Japan, Vietnam and Central Asia.The papers in this volume do not in any way attempt to offer a ""complete"" picture of the history of writing and the book in East Asia, but rather they hope to make a modest contribution by highlighting the differential developments in each of the cultural regions, as they were influenced by political, economic, social, and cultural factors.
