The aim of this master’s thesis is to examine how Swedish public libraries approach and regard lesbian pulp fiction as a genre, from both a historical and modern perspective, and also to visualize and critique the surrounding discourses that influence the perception and reception of the genre. The method is twofold and consists of qualitative interviews as well as discourse analysis inspired by Foucault. The data consists of interviews with three librarians responsible for library collections, selection and purchase of new library materials which is combined with a survey reading of Biblioteksbladet, the periodical of Svensk Biblioteksförening, from 1945–1990. Michel Foucaults theories on discourses and the principles and mechanisms of exclusion, and Pierre Bourdieus theories on taste and distinction, guide the analysis. The analysis focuses to a great extent on discursive patterns, especially concerning the relationship between popular and quality fiction, and components of Bourdieus field theory and how this contributes to the creation of taste through distinction. Throughout the analysis possible explanations regarding the position of lesbian pulp fiction are given which covers areas from classification and interpretation of literary genres to quality assessment, selection and purchase of literature. The results of the study shows that lesbian pulp fiction is quite invisible in Swedish public libraries which is mainly seen as an effect of discursive practices that surround and influence the genre such as the societal and historical view of homosexuality but also the view on popular literature. Conclusions are that librarians are not making conscious exclusions of lesbian pulp fiction per se, they are if anything quite unaware of the genre’s existence, but that the practices that shape the field of public libraries has contributed to the genre’s position. The study is a two years master’s thesis in Library and Information Science written at Uppsala university.
