The aim of this Bachelor´s thesis is to investigate how library statistics, performance measurement and indicators represent the modern public library activity. During the last decades the public library has gone through a lot of changes. Information overall has increased and new technology has been introduced into the library. This new development has had effects on the library users. The statistics reported to the Statens kulturråd (National Arts Council) has not changed in the same way. My aim is to find out if the performance measurement and indicators are up to date, and to what extent. Through qualitative interviews with two library managers and a small study of documents my aim is to answer the main questions of this thesis: • What performance measurement and indicators are used in the libraries examined?• To what extent do performance measurement and indicators relate to development and decision making? • How useful do library managers think that performance measurement and indicators are? The theoretical framework consists of Library and Information science literature address performance measurement and evaluation in public libraries. The analysis has shown that it is difficult to evaluate the public library purpose and goals, due to the difficult task of setting clearly definable goals in public libraries. Result shows that present library statistics collected by the Statens kulturråd (National Arts Council) is not up to date. Present library statistics do not represent the modern public library activity.
