This thesis aims to study how the assignment of subject headings, from the Swedish subject headings list, in the Swedish national catalog Libris relates to works of marginalized groups from an intersectional perspective. The marginalized groups represented in this study are LGBTQ as well as racified. With the term radical cataloging as the background for this thesis, I have categorized five pairs of opposite words that were the bases for my keyword search and then analyzed the subject headings for the books that my keyword searches resulted in. Using Derrida's theories of deconstruction and the perception of The Other, I have investigated which subject headings are used to describe the marginalized groups and whether these subject headings can be problematic from an intersectional perspective. The conclusion is that, although both groups are represented by a variety of subject headings, they are not always used in a correct context. There is also a lack of several subject headings which would work towards an inclusion of these marginalized groups.
