Mobile libraries in Koprivnica-Križevci County appeared in 1979 when the first bibliobus was opened within the Library and Reading Room "Fran Galović" Koprivnica. The bibliobus visits stops in suburban settlements, but also in settlements and municipalities in the vicinity of Koprivnica. Attitudes have changed over the course of their existence. At the beginning, a large number of stops were located next to the companies, while today there is only one left. However, nowadays the largest number of stops are located in kindergartens and schools. It can be concluded that children are the most numerous users of this project and therefore most of the service is tailored to them. The bibliobus service changed the vehicle in 2004, and due to wear and tear, there is a need for a new vehicle nowadays. The second mobile library in the County is the bibliobus within the City Library "Franjo Markovic" Krizevci. This bibliobus was opened in 2009 and has been operating successfully in the wider area ever since. These two mobile libraries are the only examples in Croatia where in one county there are bibliobuses within two libraries. The reason for this is the specificity of the area due to which the Koprivnica bibliobus could not be used in such terrain. For this reason, a bibliobus from Križevci was established, the vehicle of which is a van that can easily reach all remote smaller settlements. Bibliobuses are constantly working to popularize reading and provide users with access to all necessary content and library materials.
