Subject-Searching Experiences and Needs of Online Catalog Users: Implications for Library Classification. Markey, Karen Classification Dewey Decimal Classification Display Systems Information Needs Information Retrieval Library Catalogs Library Surveys Man Machine Systems Online Systems Search Strategies Subject Index Terms Use Studies This paper describes an experiment in the use of Dewey Decimal Classification in online catalogs to introduce classed approach to subject searching of library collections, enhance subject terminology indexed in online catalog, and provide possibilities for search strategies not possible through alphabetical approach of subject headings and/or keywords.
