The purpose of this Master thesis is to examine how college library managers perceive shelves of book reservation system in an integrity perspective. Privacy is an important part of everyday life in the society of today and according to some people, for example a former library lawyer in the Swedish Royal Library, these shelves conflicts with the Swedish law of Secrecy (Sekretesslagen 9 kap. 22 §). I am therefore interested in how they perceive this system: what weaknesses and strengths it has, why they implemented it, how they have interpreted this law. To answer this I have used a qualitative method called phenomenography and done interviews with five college library managers. The result shows three different ways of experiencing this system. The answers as to why they implemented the system and what strengths and weaknesses it has were quite coherent among the managers. This is a system that first and foremost is very practical for both library visitors and staff. This is one part of the development towards self-services. They showed a fear that books could be lost (a small risk), other library users could see your book reservation and that it sometimes was much work for the staff to maintain the system. The conclusion is that the three different ways of experiencing this system are: the relationship (between the law and the system) is decisive, the relationship is important but practical circumstances even more important and the relationship is insignificant. / Uppsatsnivå: D
