The support of school libraries in the modern ways of learning and the new information -communication environment is based on developing a critical mind towards given information and a creative usage of knowledge and is accomplished through Library - information education which means encouragement and promotion of reading, promotion of information literacy and cultural and public activities. The cultural and public influence of school libraries are least researched but it has experienced a lot of transformations thorough curricular changes. To establish the pre-exiting state of realized cultural and public activities of school libraries in Slavonija and Baranja this paper is based on proving the hypothesis that creatively arranged curriculum of the school library through inter-subject connection, cooperation outside of the school, using of ICT, using modern creative ways of research based learning and marketing; have a great influence in maintaining the cultural and public activity of the school and even forming the online culture of the school and general public. For analisis are used primary and secondary sources of literature, present research, information gained by descriptive analisis of library curriculum found on web sites of school libraries in Osijek, results of interviews with school librarians of Osijek primary schools and result of e-questionnaires about school libraries of Slavonija and Baranja. The results confirm the hypothesis but also imply multiple deficits of school libraries as: insufficient usage of resources given by the online environment based on modern technology; not enough connection between problem based learning, research based teaching, critical thinking and creativity; lack of openness towards initiative and the dynamic creative development; lack of involvement in international projects and lack of knowledge of different cultures and multiculture.
