The development of digital libraries has changed access and management of information in the 21st century, so the main goal of this graduation thesis is to show that the Internet as a digital medium has increased and accelerated the flow of information and digitization in higher education libraries, thereby promoting the importance of encouraging information and IT literacy among students and teaching staff. Advances in digital libraries result from the merging of technology with traditional library tools to meet the needs for faster and more accessible information for all library users. The digitization of the system itself also affected the information management system, which includes all methods, procedures for collecting and processing information about a certain source and processing data in the most efficient way for users. Nowadays, higher education libraries are increasingly oriented towards digital platforms, because they enable easier and faster communication with users. At the center of all tasks and management processes of higher education libraries are placed the competences of the employees, as well as the abilities of the users of the services provided by them. Developing information literacy and guiding users towards relevant information is the main task of higher education library employees, which is confirmed in this paper through available and appropriate data resulting from the analysis of 20 higher education libraries in the Republic of Croatia. All services, catalogs, collections and reference collections located online are available not only to the academic community but also to the general public and are indicators that support the set hypotheses, services on the websites of higher education libraries have an impact on the information management process, digitization of higher education library systems affects the faster availability of information between users and employees and that the information literacy of users of higher education libraries contributes to effective information, which will be attempted to be confirmed in this thesis.
