Ever since its original publication in Germany in 1938, Max Schweidler's Die Instandsetzung von Kupferstichen, Zeichnungen, Buchern usw. has been recognized as a seminal modern text on the conservation and restoration of works on paper. This volume, based on the authoritative revised German edition of 1950, makes Schweidler's work available in English for the first time, in a meticulously edited and annotated scholarly edition. An extensively illustrated appendix presents case studies of eleven Old Master prints that were treated using the techniques Schweidler discusses.
