The main focus of this paper will be the analysis of special libraries belonging to associations that deal with feminist topics, including the promotion of women's and human rights and the empowerment of women. Special libraries differ from other types of libraries in the ways they are founded and funded, as in the content of their collections and primary groups of users. As the Standard for Special Libraries (2021) states, they are defined as independent libraries or libraries inside a system that cover a specific scientific or artistic branch, field or area of specialized professional activity with the library services adjusted and customized to fit the needs of their users. Special libraries include scientific institute libraries, medical libraries, museum, gallery and archive libraries, theological libraries, public and state body libraries, corporate libraries, association or other civil organization libraries and others. This paper will be focusing on association libraries, more specifically non-governmental associations with the primary focus on feminist issues. Feminism arose as a movement in which women fought for their social and political rights at a time when they were oppressed and not perceived as equal to men. Today, women's issues are raised in the public space through the activities of feminist associations. According to Association Laws, the definition of an association is any form of free and voluntary association of natural or legal persons who have a common goal of solving a specific social problem. Therefore, feminist associations are all associations that deal with feminist issues with the aim of achieving gender equality, developing a just society, empowering women and promoting women's human rights. One of the tools used to achieve these goals are special libraries, the launching of which helps educate users about feminist issues in an accessible way. The research part of the paper will provide an insight into the way feminist association libraries in Croatia operate.
