- Abstract
- Purpose - The purpose of this paper is to examine challenges facing bibliographic classification at both the practical and theoretical levels. At the practical level, libraries are increasingly dispensing with classifying books. At the theoretical level, many researchers, managers, and users believe that the activity of "classification" is not worth the effort, as search engines can be improved without the heavy cost of providing metadata. Design/methodology/approach - The basic issue in classification is seen as providing criteria for deciding whether A should be classified as X. Such decisions are considered to be dependent on the purpose and values inherent in the specific classification process. These decisions are not independent of theories and values in the document being classified, but are dependent on an interpretation of the discourses within those documents. Findings - At the practical level, there is a need to provide high-quality control mechanisms. At the theoretical level, there is a need to establish the basis of each decision, and to change the philosophy of classification from being based on "standardisation" to being based on classifications tailored to different domains and purposes. Evidence-based practice provides an example of the importance of classifying documents according to research methods. Originality/value - Solving both the practical (organisational) and the theoretical problems facing classification is necessary if the field is to survive both as a practice and as an academic subject within library and information science. This article presents strategies designed to tackle these challenges.

- Abstract
- Much of the literature of information science and knowledge organization has accepted and built upon Elaine Svenonius's (2004) claim that "paradigmatic relationships are those that are context-free, definitional, and true in all possible worlds" (p. 583). At the same time, the literature demonstrates a common understanding that paradigmatic relations are the kinds of semantic relations used in thesauri and other knowledge organization systems (including equivalence relations, hierarchical relations, and associative relations). This understanding is problematic and harmful because it directs attention away from the empirical and contextual basis for knowledge-organizing systems. Whether A is a kind of X is certainly not context-free and definitional in empirical sciences or in much everyday information. Semantic relations are theory-dependent and, in biology, for example, a scientific revolution has taken place in which many relations have changed following the new taxonomic paradigm named "cladism." This biological example is not an exception, but the norm. Semantic relations including paradigmatic relations are not a priori but are dependent on subject knowledge, scientific findings, and paradigms. As long as information scientists and knowledge organizers isolate themselves from subject knowledge, knowledge organization cannot possibly progress.
