The technical problems confronting different societies and periods, and the measures taken to solve them form the concern of this annual collection of essays. Volumes contain technical articles ranging widely in subject, time and region, as well as general papers on the history of technology. In addition to dealing with the history of technical discovery and change, History of Technology also explores the relations of technology to other aspects of life -- social, cultural and economic -- and shows how technological development has shaped, and been shaped by, the society in which it occurred.
