This book, first published in 1990, examines the relationship between sci-tech materials and trade literature, commonly called manufacturers’ catalogues. Because very little has been published about the value and nature of trade literature in regard to sci-tech libraries, this volume is important in informing librarians about a little-known segment of the larger picture of sci-tech information sources, thus adding to the value of their services to their clients. It addresses the problems of handling sci-tech trade literature in a corporate technical library, a large public library, and a government library devoted to American history. Experts offer practical advice on selecting and organizing trade literature and on managing the growth and extent of a collection of trade literature. They discuss modern literature and older publications, which often have great historical value. Libraries that collect both old and new materials are identified, as are publishers of trade literature. The book also focuses on how a publisher of classic trade literature views its role.
