This paper analyzes the public library as the cultural center of its community with reference to the Biograd na Moru Public Library. Cultural libraries contribute to the quality of life of an individual in all areas of life, and the local community should be actively involved in the planning and design of library activities. With its cultural influence, the library also influences the "visibility" of the library within its community. The first part of the thesis deals with the very concept of the public library and its development through history. The following is the development of the social and cultural role and the challenges the library faces in the digital age. After elaborating the tasks, services and activities that the library conducts as the center of its community, an example from the practice of the Biograd na Moru Public Library will be given. The second part of the paper deals with the research of the Biograd na Moru Public Library as a cultural center of its community. The aim of the research was to determine the impact of library programs on the perception of library users as a cultural center, their use of library services and the presence of cultural programs. Each library must have clear goals in achieving its role as a cultural center and must be open to all users equally and encourage the interest of citizens to participate in shaping the quality of life of their community. In order for the library to make the most of its potential, it needs to be acquainted at every moment with the changes that take place in society and within its community. Aside from its quality programs and activities, it helps in the cultural uplift of its community, at the same time it creates the reputation and the conditions to be the cultural center of its community.
