This is an authoritative and insightful survey of the evolving field of photograph conservation. This volume is the first publication to chronicle the emergence and systematic development of photograph conservation as a profession. In 72 essential texts from the 19th century to the present day, this anthology collects key writings that have influenced both the philosophical and the practical aspects of conserving photographs. The materials were carefully selected by the editors along with an advisory board of international experts and include a number - particularly the lectures, memos, and letters - that have never been published before. Many of the topics - safe environmental parameters, silver image permanence, and proper treatment methods - have been debated since the introduction of photography. By promoting an understanding of these issues, this volume seeks to advance the education of rising conservation professionals, inspire new scholarship, and contribute to the field's ongoing evolution.
