The paper is a review of bibliographical publications relating to transparent papers during the period 1960 to 1999. Emphasis is placed on conservation treatments. An introductory chapter covering the history and technology of these papers is followed by a description of types of degradation frequently encountered and a short paragraph dedicated to analysis. Subsequent chapters discuss conservation treatments, including dry cleaning, humidification and flattening, washing and deacidification, lining, local repairs, resizing, facing, solvent use and bleaching. A discussion of housing and storage methods completes the review.
