The Florentine
Renaissance Libraries, a Picasso collage, and a set of 16th-century prints rescued from the north-polar ice all owe their present existence to the painstaking work of paper conservators.
Richard Fisher examines the aims and techniques of these specialists whose task it is not only to rescue such priceless articles as these, but also to prevent the ever-growing collections in our libraries and archives from simply crumbling away.
