Regarding the assessment of services provided by the university library, 33.7% of doctoral students were not satisfied about the availability of documents in their special fields. Thirty two per cent had difficulty in locating documents, while 46.1% reported a lack of training in the tools of documentary research. These results are explained by the widespread use of the Internet by PhD students for academic research; 39.5% use the Internet daily for between two to four hours, without it affecting the importance of the primary document (paper). In fact, 45% of doctoral students appreciate the paper document; this percentage is slightly lower for electronic document amateurs who are mostly the scientists (54.3%).
