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 post-graduate students. Results showed that Greek post-graduate students from different fields of study chose the Internet as their primary information source for a number of reasons but mainly: for the provision of creditable and up-to-date information, for easy access to information at home, for the time of day they can access the material and for fast information retrieval. Although the Greek post-graduate students believed the Greek information network to be satisfactory up to a degree, this paper identifies that greater access to Internet resources, training programs providing students with tools to effectively use the network's resources and more online databases, combined with a historical and statistical database of libraries’ online catalogs are key issues in improving both information source performance and the link between strategy and implementation.
