This thesis aims to analyze public librarians' experiences of weeding in a Swedish public library organization that uses logistics systems for circulation, such as centralized acquisitions, floating collections and intelligent distribution algorithms (IMMS). The theoretical framework is influenced by institutional theory and previous studies of weeding in libraries. The study explores how public librarians describe and motivate their weeding decisions, relating it to overlapping institutional logics. The researchers conducted interviews with seven public librarians working in Gothenburg. Thematic analysis was used to identify relevant themes from the data, resulting in the description of five overlapping institutional logics of weeding in the organization: physical condition, availability & demand, reading promotion, quality & transfer of knowledge and mental shortcuts & professional discretion. The use of the logistics systems have resulted in an uneven distribution of material that also influences the librarians' perception and practice of weeding in their local branches. The results further show that the existing tools and guidelines in the organization are used as a complement to the librarians' own knowledge about the collection and that the weeding criteria and statistical tools do not apply to all weeding cases, causing professional dilemmas.
