Abstract
This paper reports a computer-assisted printed index emphasizing expanded subject access to the more than 6.000 titles in the Iowa State University Library reference collection. The index displays abbreviated-length records and is designed to complement existing catalogs with a minimum of duplication of information. The limitations of subject access to reference materials via LCSH is discussed and a system for assigning subject descriptors to reference titles is described
