    Area of Science:

    • Medical Informatics
    • Information Science
    • Library Science

    Background:

    • MEDLINE (Medical Literature Analysis and Retrieval System Online) has evolved significantly in its search philosophy and methodology.
    • The transition from batch-mode linear operations to the interactive, random-access capabilities of MEDLARS II presented new challenges and opportunities for searchers.

    Purpose of the Study:

    • To describe the development of MEDLINE searching philosophy and methodology.
    • To discuss searcher requirements and capabilities in adapting to new search modes.
    • To provide a detailed tutorial on effective search formulation and retrieval analysis.

    Main Methods:

    • Exploration of searcher requirements and capabilities during the transition to MEDLARS II.
    • Detailed tutorial covering elements of search formulation: requestor interview, query analysis, terminology selection, logic formulation, indexing adaptation, man-machine interface, and retrieval analysis.

  • Examination of techniques used for producing recurring bibliographies (RBs) and literature searches (LSs).

    • Main Results:

    • MEDLINE searching has advanced from linear, batch operations to iterative, random-access retrieval via MEDLARS II.
    • Comprehensive search formulation involves multiple steps, including user interaction, query refinement, and sophisticated terminology selection.
    • MEDLINE supports the production of recurring bibliographies (e.g., Index Medicus) and ad-hoc literature searches, with 27 RBs in production and over 375 LSs produced by 1977.

    Conclusions:

    • The iterative, random-access mode of MEDLARS II enhances MEDLINE searching capabilities.
    • Effective MEDLINE searching requires a systematic approach encompassing query analysis, precise terminology, and logical formulation.
    • MEDLINE's retrieval and publication systems efficiently produce valuable bibliographical resources for the medical community.
