• The paper describes qualitative methods of modern library collections (produced after the year 1800) survey in The National Library of the Czech Republic in Prague. Each book is primarily composed of paper sheets and bookbinding. In modern library collections bookbinding usually contains parts composed of synthetic materials. Different types of materials have different mechanisms of degradation. Therefore, the main objectives of this work are nondestructive identification of synthetic materials in bookbinding, their degradation processes, and methods of conservation, conditions of storage, and preventive care as well. Based on the preliminary results of the collection survey in the National Library of the Czech Republic, the most usual types of synthetic materials in bookbinding are cellulose nitrate, cellulose acetate, polyethylene, polyurethane, polymethylmethacrylate, and polyvinyl chloride, both of solid and plasticized type. For faster survey of the collections and deeper information is used new instruments for modern library collection survey and preservation – SurveNIR measuring system. SurveNIR measuring system is used for determination of paper properties and identification of plastic materials using chemometric and comparison with material standards. It can identify more than 45 different types of plastics. It is a nondestructive method, very fast, and it is possible to obtain results in a few seconds of measuring. The SurveNIR system was developed in the European project.
