The main objective of this article is to provide an overview of potential financing sources for library projects which can be executed by public universities. The most important authorising officers of the funds for pro-development activities of libraries are state-level and regional institutions represented by the Ministry of Science and Higher Education, the Ministry of Culture and National Heritage, Digital Poland Project Centre, the National Centre for Research and Development and Marshall’s Offices. The applied method of analysis and synthesis of the acts, regulations and guidelines within the scope of eligible expenditure and adetailed description of national and regional operational projects has allowed for the types of projects which can be financed form non-university national and European resources to be identified. The national and regional level institutions supporting the activities for the development of libraries are mainly focused on the projects concerned with preservation of the unique library resources of high importance for science or its heritage, developing scientific library resources and making them available in digital form, as well as increasing access to data bases which contain scientific information, including Virtual Library of Science. The above mentioned institutions finance or co-finance both the building and the expansion of interoperational scientific digital repositories of regional or national scope, which are user-oriented and co-finance the activities for the improvement of skills in managing information and using professional data bases in educational process. The variety of project types which are subject to external financing makes it possible to execute projects which are in accordance with current strategies for the development of libraries, expressing their current and future plans. The research conducted has shown current availability of funds for the activities for development of scientific libraries on the level of both state and regional institutions. The availability of these funds by means of competition enables the execution of innovative projects, the main purpose of which should be to achieve competitive advantage of specific academic centres on the market of library services in Poland. The research has also confirmed the possibility of obtaining funding form the European or national funds up to 100% of eligible expenditure of the projects concerned first of all with the development of e-science. It is particularly important in the situation when university budgets cannot ensure financing for all the expenditure connected with pro-development needs of their libraries.
