- A Comparative Analysis of Interactive Storage and Retrieval Systems with Implications for BCN Design. Seiden, Herbert R. Automation Comparative Analysis Information Networks Information Retrieval Information Storage Medical Libraries Systems Development The work reported is part of a series of studies aimed at providing information and assistance to the National Library of Medicine (NLM) in planning the Biomedical Communications Network (BCN). The first part reviews the literature on systems relevant to BCN design, documents System Development Corporation's position with respect to certain concepts of bibliographic retrieval as they relate to BCN planning and provides a basis for better understanding of the comparisons. The second part contains comparisons of various systems based on data available in open sources. Over 150 systems were reviewed. Of these, 26 general-purpose and 11 bibliographic systems were selected for comparison, based on criteria described in the study. Implications for system design, for the BCN user, and for network planning are discussed in the third part. Some of the major points are: (1) NLM should stay with the bibliographic retrieval design; (2) a unified network concept should be developed and implemented; (3) there is a need for standards and specifications for inputs, thesauri and unit records; (4) users should be provided more direct access to the files on an interactive basis and (5) some files should be maintained centrally while others should be duplicated at several centers.
