The Swedish Library Classification System, known as the SAB-system, can be viewed as a product of the cultural and social norms and values in Sweden during the time in which it was created and subsequently reviewed. The main purpose of this master’s thesis is to examine the archaeology section J in the SAB-system, in order to observe if values and norms within this discipline had any impact on the Swedish Library classification system. Our intention is therefore to verify any correspondence between the choice of topics and hierarchical structure of that section, and the values and norms that ruled the Swedish society during the 20th century at large but with particular emphasis to the academic discipline of Archaeology. At the present, Archaeology is often disputed as a value-free interpretive science. Modern scientists are wondering if archaeological conclusions have ever been apolitical. This paper explores if altered attitudes and the socio-political changes through history, can be seen in the Swedish Library classification system. The imperialism, nationalism and left wing radicalization are some of the movements that are examined in this paper. The approach of this study is hermeneutical due to the importance of understanding the context. Literary studies of the history of Archaeology and Library and Information science have been used, and a comparison between all of the eight editions of the SAB-system has been conducted. The result of this study shows that even though the political and ideological changes had a great impact on the Archaeology as a science, there is little evidence that shows the dependency of the archaeology section in the SAB-system from the academic discipline itself. Regardless, the result also shows that the political and ideological changes through the 20th century greatly influenced the outlines of that particular section of the Swedish classification system.
