The objective of this Bachelor’s thesis is to investigate how the public library in Luleå has set about implementing an alternative classification system for its children's books section and to explore why this was done. We wanted to investigate both how they have adapted the new system to the children's own way of seeking information and the library personnel's experience of using the new shelving system. We have done seven interviews to answer these questions and our choice of literature is intended to put the process of change into a wider context. The answers show that the library was dissatisfied with the former system and have instead expressed a desire to shift the focus of their classification system to their users. A significant factor behind the change was that they wanted to make children the basis of the new system. Here, they have instigated a change to the whole children's section and this new system is founded upon children's behaviour with regard to searching for information. The broad subject groupings have been given names that the children themselves use when they ask for books and, in order to facilitate the actual finding of the books on the shelves, the books have easily-recognisable symbols on the spine. According to our research, the staff in Luleå has found that both the users and they themselves are pleased with the new system, although an official evaluation has yet to be undertaken. We conclude that the advantages of the alternative systems outweigh the disadvantages. / Uppsatsnivå: C
