The system of PhD training was transformed by the law LXXX. of 1993 and the related regulations in Hungary. As a consequence of this, a period had come to an end in 1996 in the history of doctoral dissertations written In the field of library science. After the survey of János Balázs (Könyvtári Figyelö, 1991. no. 2.) made in 1991 regarding dissertations from the period 1958-1990, dissertations prepared since 1991 are analysed in the present study. The following data were gathered with respect to the dissertations: the rate of library science graduates and dissertations prepared, the year of acceptance, the age of those receiving the degree, the time between graduating and getting the degree, the relation between the theses and the dissertation, and the length of dissertations. The study analyses the content of the 25 dissertations, and introduces some new groups from this point of view (such as the history of censorship, the history of related disciplines, user education, integrated library systems, new tools in Information processing). The last two categories indicate the shift of library science towards informatics and information science. The two surveys throw light on the need of the abstracting of the 160 doctoral dissertations written in library science, and the publication of the summaries.
