The objective of this work is to provide a basis for the model of a new, efficient way of connecting electrical-engineering libraries. The research results could contribute to the creation of an electrical engeering libraries network in Croatia and its merging with modern international development trends. In the introductory chapter of the study the impact of scientific and technological development on society in general was explained. Prior to the presentation of the objectives and preliminary hypothesis of this research, the consequence of technological change on the development of science, technology and scientific research in Croatia were mentioned. In the following chapter Historical development the mainstream of development of academic education and scientific research in the field of electro-engineering in Croatia were presented. Special attention was paid to the foundation and development of the Faculty of Electrical Engineering at the University of Zagreb, University of Osijek, University of Rijeka and University of Split. Historical research in this chapter was based on available documentation, Universities’ archives, and numerous publications. In the following third chapter, the main characteristics of worldwide library practice in the field of electro-engineering were contrasted with the experiences in the related libraries in Croatia. Available information and on library practice in electricalengineering libraries in Croatia was presented and explained. The main chapter of the work, the fourth chapter, presents a user study at four universities in Croatia (University of Zagreb, University of Osijek, University of Rijeka, University of Split). In this comprehensive user study library services in the field of electrical-engineering were targeted. The statistics on library staff, users, the number and purpose of visits, and user satisfaction with a number of other parameters were measured, compared and analysed. The study was based upon a survey (questionnaires and interviews) and research on library circulation data. Over six hundreds students were surveyed and questionnaires were collected and analysed. Students were questioned on the purpose of their visit to the library and their reading interests. Furthermore they were asked to estimate the level of their satisfaction with the service provided. In addition 17 questionnaires and interviews with library staff and the heads of academic management were analysed and compared. The evaluation of the research results was presented in the fifth chapter. As a result, a new efficient model of the networked electric-engineering libraries was suggested which could make use of new information and communication technology. The model would be built around a central information service for the field of electricalengineering which could function as the nucleus of a future central library. In the conclusion chapter the results of the research were summarized and various problems regarding research methodology were pointed out. The need for the further research was expressed as more profound analysis would be necessary in many issues.
