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. The majority of the informants describe EBLIP as a concept by which they mean an approach, a process and skills training. With regard to the EBP process two approaches could be distinguished. First, to follow the EBP process stepwise with the aim of changing the work. Second, to elaborate on each step aiming to introduce the process and training skills in using scientific material and EBLIP. A number of activities at the different libraries have been identified to be included in the implementation of EBLIP. These activities seem to serve as strategies to bridge most, the extent not established, of the different forms of gaps between research and practice.
