The Eötvös Loránd University has always been considered as one of Hungary's oldest and most prestigious universities. The Department of Library and Information Science (DLIS) of Eötvös Loránd University has also accomplished an outstanding mission in the introduction and implementation of library education in Hungary, and until 1989 it was the only university department providing such tuition and research. Not surprisingly, the DLIS has always been either the pioneer or the leading force in library science Ph.D. and other doctorial activities. Before the change of the political system, more exactly before 1993, there were three types of advanced scientific degrees in Hungary: 1. doctor universitatis (university doctor) abbreviated as: dr. univ.; 2. candidatus scientiarum (candidate of sciences for the doctor's degree of the Hungarian Academy of Science) abbreviated as C.Sc.; 3. doctor scientiarum (doctor of sciences of the Hungarian Academy of Science) abbreviated as D.Sc. The DLIS of Eötvös Loránd University not only issued 164 doctor universitatis diplomas, but worked in the closest cooperation with the Academy of Science to provide C.Sc. and D.Sc. degrees to librarians. Since 1997, the Department of Library and Information Science of Eötvös Loránd University has set up its own multi- and interdisciplinary doctoral program within the framework of the Ph.D. School for Literary Studies at the Faculty of Humanities. The doctor's degree issued by Hungarian universities corresponds in every respect to what is defined and recognized internationally as a Ph.D. degree and the Hungarian system meets all the requirements of the international academic standards. So far nine Ph.D. students have defended their dissertations. The majority of the specialists taking part in their qualification belong to the natural and applied sciences.
