The library network consists of central regional, central, local, and mobile libraries. Mobile library performs its activity in the areas with less than 1500 inhabitants, and with the distance of more than 4 kilometres from a library. The mobile library can be carried out in the form of bibliobus; that is a vehicle adapted for performing library activities. Bibliobus represents an economical and effective solution for a better extent of the library activities in the area. The aim of the research is to check the current extent of the library activities, check advisability of the bibliobus introduction, and to plan its stops in the municipalities of Kranj, Cerklje na Gorenjskem, Naklo, Preddvor, Šenčur and Jezersko. Based on the data in the COBISS system, we have performed two analyses of the current mobile library operation. Further, we have also performed a interview with the performers of the library activities in the borrowing points of the mobile collection. The second part is comprised of the local environment analysis. The outcome of the master's thesis is a plan of the bibliobus stops network in the area of the municipalities of Kranj, Cerklje na Gorenjskem, Naklo, Preddvor, Šenčur, and Jezersko. A total of 52 stops are planed; namely 21 stops in the municipality of Kranj, 11 stops in the municipality of Cerklje na Gorenjskem, 4 stops in the municipality of Naklo, 6 stops in the municipality of Preddvor, 9 stops in the municipality of Šenčur, and 1 stop in the municipality of Jezersko.
