Relevance is one of the key categories of information science, traditionally expressing the relation between searched and found information, the relation of correspondence, need, usability. Qualitative research based on interviews with 21 doctoral students has been carried out at the Comenius University in Bratislava, Faculty of Philosophy, in 2006. It was aimed at understanding how the students perceive the concept of relevance and the criteria of judging the relevance of information in traditional and electronic environments. The preliminary results of phenomenographical analysis performed on the data gathered during the interviews indicate some differences. In printed information resources, judging of textual, content characteristics of information serves as a primary criterion of relevance. On the other hand, in the electronic environment the users pay more attention to the aspects of information resources which are not directly connected with their content. Accent on the quality of the resource, its institutional affiliation, is linked with a need of assessing the reliability, trustworthiness of network information resources. Analysis of processes connected with relevance judgments show some parallels with Saracevic’s relevance typology. The differences in criteria applied on judging relevance in traditional and electronic information resources are manifested mostly on higher relevance levels – cognitive, situational and motivational. For some users, the relevance judgment equals to the assessment of formal characteristics and basic content correspondence of information resource with the inquiry, and it ends there. For the others, the thorough understanding of content is a part of this process as well.
