This article reviews the practices of subject assignment by the two main Norwegian cataloging agencies serving the public library domain, Biblioteksentralen and Bokbasen, analyzing 47,235 records representing media cataloged by both agencies, published between 2012 and 2019. In addition to descriptive statistics representing these practices, we apply the Panofsky/Shatford model, previously used in the analysis of artworks and images, to distinguish aspects of these practices associated with levels of meaning. We find that Biblioteksentralen tends to use more abstract terms in their descriptions, while Bokbasen tends to use more general terms.
