Abstract

Free text searching with keywords in a complete data store is not necessarily the best automatic retrieval method. There must be a proper classification of documents and concepts and the use of a proper classification system avoids problems of terminological deficiency. The dialogue search form makes the on-line catalogue a new information medium. A bibliographic unit must be created with as many search access points as possible, using verbal and classificatory search elements. Verbal search categories must include free text elements for individual search access requirements and a controlled vocabulary with syntactic connections. Classified data should consist of a universal classification system with clear structural notation for access and surface searching, together with several specialist subject classifications for differentiated documentation and retrieval. The universal classification needs no detailed subdivision: it serves mainly as a guide and entry to the detailed sub-systems

Abstract

In the DDC Online Project, subject searching and browsing of DDC schedules and relative index were featured in an experimental online catalog. The effectiveness of this DDC in an online catalog was tested in online retrieval experiments at four participating libraries. These experiments provided data for analyses of subject searchers' use of a library classification in the information retrieval environment of an online catalog. Recommendations were provided for the enhancement of bibliographic records, online catalogs, and online cataloging systems with a library classification. In this paper, subject searchers' use of the subject outline search capability of the experimental online catalog is described. This capability was unique to the experimental online catalog and all other online catalogs, because it referred searchers to online displays of the classification schedules based on their entry of subject terms. Failure analyses of subject outline searches demonstrated its specific strenghts and weaknesses. Users' postsearch interview comments highlighted their experiences and their satisfaction with this search. Based on the failure analyses and users' interview comments, recommendations are provided for the improvement of the subject outline search in online catalogs.

Abstract

Research leading to a detailed content analysis and profile of the Library of Congress Classification schedules. A description of the design, methodology, and preliminary findings of research in progress. Final results of the study are expected to aid the Library of Congress in the development of a MARC format for its classification schedules and in the conversion of the schedules into machine-readable form. LC's ultimate goal is the design of an integrated system which will permit on-line editing, maintenance, and control of the schedules, on-line classification and shelflisting procedures, the production of the schedules in two or more physical formats, and the use of LCC to enhance search capabilities in on-line catalogues.
