The Social Science Section of the Association of Hungarian Librarians held a meeting in spring, 1999 entitled -Retroconversion: achievements and perspectives in libraries supported by the National Cultural Fund'. In 1995 the Fund invited applications from some major libraries for the input of 8000 records of foreign books into an on-line catalogue within a year. 2 million forints were offered as a support for participating libraries. At the meeting Gomba Szabolcsné was the first to talk about the essence of retroconversion, and to give an account of the retroconversion started at the Central library of the Kossuth Lajos University, Debrecen, then representatives of other participating libraries (e.g. that of the National Technical Information Centre and Library, the library of the Hungarian Academy of Sciences, the National Pedagogical Library and Museum, the Metropolitan Szabó Ervin Library, the National Agricultural Library, the Library of the Budapest Technical University, the Library of the Budapest University of Economics, and the library of the Parliament) summarised their experiences.
