The purpose of this paper is to investigate, through empirical analysis, whether or not post-graduate students choose information technology or other information sources such as home institution libraries for the purposes of learning, expanding their knowledge and/or completing their studies. A survey was conducted to gather primary source data for the paper, Questionnaires were administered to 211 education postgraduate students. Results showed that Greek postgraduate students with different fields of study chose the Internet as their primary information source for a number of reasons but mainly: the provision of creditable and up-to-date information, easy access to information at home, round-the-clock availability, and fast information retrieval, Significant association was found between their selected information source and field of study, Although the Greek postgraduate students believed that the Greek information net-work is satisfactory to a certain degree, the paper identifies a number of factors having a significant and positive influence on the performance of information sources and on the link between strategy and implementation such as greater access to Internet resources, training programs designed to provide the students with tools to overcome problems in their effective use of the network resources, and more online databases that include a historical and statistical database of libraries' online catalogs.
