In every community, libraries should be better positioned on the scale of social values. In addition to taking on an educational, informational and cultural function, they also serve as entertainment. This work covers the beginning of the University Library in Pula, which was greatly influenced by the historical development of the city, also intertwined between the different national structure of the population that formed an integral part of the community. This type of multiculturalism was also reflected in the cultural aspect of the Library, by completing its diverse material, which has largely been preserved to this day. Since the beginning of its activities, primarily due to the lack of adequate space due to the influx of a growing contingent of library materials, the library has changed its location several times to eventually position itself above the main city promenade near one of Pula's many fortifications, better known as Kastel. In addition to the extremely rich library fund, which over time has become accompanied by the development of digitalization in storage and accessibility of materials to users through the pilot project Istrian Newspapers Online, the pride of the library is the Histrica Regional collection Histrica, which has great importance and pride for the citizens of Pula and Istrian County. A major turning point in the work of the Library was the annexation of the library to the Juraj Dobrila University in Pula in 2006., which consequently contributed to greater interest in its material, including the Histrica Local Collection.
