    Abstract
    Purpose - To suggest that a theory of classification for information retrieval (IR), asked for by Spärck Jones in a 1970 paper, presupposes a full implementation of a pragmatic understanding. Part of the Journal of Documentation celebration, "60 years of the best in information research". Design/methodology/approach - Literature-based conceptual analysis, taking Sparck Jones as its starting-point. Analysis involves distinctions between "positivism" and "pragmatism" and "classical" versus Kuhnian understandings of concepts. Findings - Classification, both manual and automatic, for retrieval benefits from drawing upon a combination of qualitative and quantitative techniques, a consideration of theories of meaning, and the adding of top-down approaches to IR in which divisions of labour, domains, traditions, genres, document architectures etc. are included as analytical elements and in which specific IR algorithms are based on the examination of specific literatures. Introduces an example illustrating the consequences of a full implementation of a pragmatist understanding when handling homonyms. Practical implications - Outlines how to classify from a pragmatic-philosophical point of view. Originality/value - Provides, emphasizing a pragmatic understanding, insights of importance to classification for retrieval, both manual and automatic. - Vgl. auch: Szostak, R.: Classification, interdisciplinarity, and the study of science.
