This essay is about the mobile library in three communities of a district. Interviews with the help of research questions are used as a data collection method to gather information on how the mobile library works, which possibilities for evolution it has to better satisfy their users’ needs and which place the mobile library occupies in its context to the main library and its branches. As a theoretical background the work of Andersson & Skot-Hansen is used to illuminate the mobile library’s different usages, determined by four centres, the centre of culture, the centre of knowledge, the centre of information and the centre of social interaction. Two of three communities will be buying new bookmobiles for the mobile library in 2018 and with the new equipment the mobile library will be able to offer additional services. The mobile library is no longer only an instrument to deliver books and other media, it grows to a multiroom with multiple opportunities, able to host cultural and educational events while offering digital services, information and a meeting place. Faced with closing down library branches the mobile library is either part of the centralisation process of the main library or part of the decentralisation process of the main library filling its own roll in the work towards its users. As part of the decentralisation process the mobile library is considered a library branch, not stationary but mobile, one of its many advantages in the work to deliver its services directly to users anywhere.
