Journal of library automation [June 1975]


Copyright (c) 1975 Information Science and Automation Division

Abstract: MEDLARS II, the replacement for the MEDLARS system used by the National Library of Medicine over the past decade, incorporates a number of major advances in the state of the art for massive information retrieval systems: on-line access to a number of very large bibliographic files, an efficient throughput figure, validation and mapping of inputs against authority files, and modularity and parametric programming to provide the flexibility needed to support future system enhancements. Major MEDLARS II subsystems described are: (1) specification maintenance, (2) input and release, (3) file maintenance, (4) retrieval, (5) publication production, and (6) management reporting. The MEDLARS II retrieval subsystem (ELHILL) incorporated the results of the experimental AIM-TWX service.
