Abstract: A computer-generated newspaper index implemented at Iowa State University to replace a card file system is described. The mechanized system employs an algorithmic indexing approach which facilitates data input procedures. The indexer is required to directly select natural-language terms or phrases appearing in the headline or text of the newspaper article as subject descriptors. A comparison with the former card file system indicates that the computer-produced index is cost competitive and provides a more effective retrieval system.
