![]() It will be revised as new information and products become available. The information in this section reflects our current understanding of the storage requirements for paper. The American Institute for Conservation of Historic and Artistic Works (AIC) provides an online "Find a Conservator" tool that provides the names of conservators in your region. If your collections are extensive, in poor condition, or include works of art, it would be advisable to consult a professional conservator. No introduction, however, can provide all the answers. ![]() It is oriented toward collectors, artists, archivists, and librarians who are new to the field of preservation. The goal of this section is to provide the background information necessary to select the most appropriate storage systems for flat paper (storage of photographs is addressed in a later section of this publication). Storage enclosures lessen the effects of fluctuations in temperature and humidity and provide protection against abrasion and handling, but they must be strong, durable, and chemically stable so that they do not damage the materials they enclose. These include providing a cool, dry, clean, dark, and stable environment protecting collections from disaster handling collections carefully choosing appropriate storage furniture and using protective storage enclosures. There are a number of steps that can be taken to preserve vulnerable paper collections. Pollutants in the air and/or direct contact with poor-quality storage enclosures also cause discoloration and embrittlement of paper. ![]() Unlike earlier papers, which were made of higher-quality fibers (commonly called rag papers), wood-pulp papers contain natural impurities and byproducts of the manufacturing process that break down to form acids in the presence of heat, light, and moisture in the air. Some types of paper are particularly vulnerable-for example, the acidic wood-pulp paper that was produced throughout much of the 19th and 20th centuries. Documents, manuscripts, prints, drawings, pamphlets, periodicals, newspapers, postcards and ephemera are typically made of paper-an organic substance that is vulnerable to deterioration over time.Īll paper will deteriorate if mistreated or stored improperly.
