PurposeIn this study, the authors report visitors' and personnel's safety experiences and concerns in order to understand the safety conditions of a library.Design/methodology/approachThe analysis is based on answers from a small sample survey of library visitors, interviews with the personnel and incidents recorded in a library in Stockholm the capital of Sweden.FindingsDealing with visitors under influence of drugs/alcohol or feeling intimidated by groups of young individuals are examples of situations in which the staff feel most unsafe. Visitors declare witnessing problems of public disturbance and disorderly conduct, fights and other types of aggression. Although the vast majority of visitors declare feeling safe in the library, their perceptions vary according to the library's environment and their individual characteristics, including their previous victimization.Practical implicationsThe study is novel because it indicates the importance of the environment to ensure the safety conditions of the library for both visitors and staff. Finally, research on safety in libraries is often from North America and Western European contexts, while this study contributes to the international literature by illustrating libraries in a Nordic European context.Social implicationsThe study indicates that more social control, both formal and informal, is at the top of the list of recommendations for visitors. Among personnel, recommendations include the need for cooperation with other local actors to solve problems in surrounding areas as well as better education for librarians in dealing with the current safety challenges of libraries as multifunctional public facilities.Originality/valueCombine visitors' and personnel's safety experiences to better understand the safety conditions of a public library.
