KvinnSam is stated to have had an important role in laying the foundation of academic gender studies. The initial organization was founded relatively long before the subject entered the academic arena, which places the knowledge organization of the field prior to the authoritative demand for it. This study aims to analyze events, initiated by the library, significant to the academic establishment of gender research from a discursive perspective. By utilizing the concepts of documentality and legitimacy, and cognitive authority the analysis answers the question of what active function and significance the library has had in establishing the academic field of gender studies. The empirical material is gathered from the libraries own archives on historical women associations, published accounts of librarians engaged in the organization and articles and debate pieces published in media. The historical method used results in no produced material but a controlled selection based on the theoretical approach and the placement of the accounts in a contemporary context. The analysis results in a review of both the official and informal constitutive forms the library has been situated in and its effects on legitimacy. It also covers the relations to the academic sphere as cognitive authority and the process of making an uninstitutionalised subject field considered veracious science. The most valuable conclusions are the library’s function to describe and value knowledge and thereby declare their scientific relevance, as well as the discursive significance of stating the field as a possible research domain by creating an academic infrastructure for it.
