Purpose -To examine some of the ways in which electronic resources have made an impact on traditional interlending practices and how some userpractices have begun to change. Design/methodology/approach -This study uses both quantitative and qualitative data. The qualitative data were gathered through a questionnaire about the impact of electronic resources and the use of ILL. Comparisons of change were made with document suppliers. Findings -The electronic full-text is as yet unable to fully meet the needs of the researchers. Until full-text can approximate what is available in print both in journals and in monographs, the need for document delivery services will remain. Originality/value -An insight into the state of e-journal penetration and its impact on document delivery in Spain -a country where few studies have been carried out in this area.
