The purpose of this thesis is to shed light on how evidence-based librarian and information practice (EBLIP) is understood and practised at some Swedish hospital libraries, and also to analyze how EBLIP functions as a strategy to bridge the gap between research and practice as described by Haddow & Klobas. The theoretical framework for the study is partly based on Haddow & Klobas description of the gap between research and practice in the field of LIS and partly a description of the EBP-process which plays a key role in the use of EBLIP. Interviews have been done with four people, three librarians, all with management experience, and an academic development officer, active at three different hospital libraries where EBLIP is practiced. All informants believed that it is important to make use of research results in order to improve services and practice. In their efforts to apply the research findings the informants face a number of hindrances, which indicates a gap between research and practice.
