correspondence as well as field trips abroad. This year we have visited libraries in Leningrad, in Paris and in the GDR. In the frame of our newspaper preservation program 1,3 mn pages have been microfilmed. Approximately 260,000 frames have been produced from the documents of our special collections, such as manuscripts, early printings, theatre documents and music documents, etc. Colour frames were made from graphic posters of historical or artistic value. As a priced service, we have produced 610,000 microfilm frames for other Hungarian libraries to fill gaps in their holdings. Interlibrary (Central) Services Of the 1,2 mn legal deposit copies supplied by Hungarian printing offices, we have distributed approx. 1 mn among libraries in accordance with their profile of acquisition. The Hungarian ISBN and ISSN Office issued 8,532 and 605 new codes respectively. This year the Hungarian ISSN Office has begun issuing international code numbers to periodicals of the socalled "second category". In the Union Catalogue of Foreign Books 177,000 new data received from 139 Hungarian libraries have been registered. We have provided location information in 18,500 cases. The two numbers of the semiannual location index of foreign handbooks in the humanities, Külföldi Társadalomtudományi Kézikönyvek have been published. The Union Catalogue of Foreign Periodicals has registered 80,000 new data and has given information in about 14,000 cases. The location index of the current foreign periodicals, Külföldi Folyóiratok a Magyar Könyvtárakban 1978/79 was published this year. The compilation of a retrospective location index (Foreign Periodicals in Hungarian Libraries from the 17th century to 1970) has been going on. The number of the data sheets returned to the Central Registration Bureau of Hungarian Libraries amounts to 2,795, i.e. we have detailed information about as many libraries as that. We started to register ecclesiastical libraries as well. It is characteristic of our interlibrary loan services that the number of the requests forwarded abroad (11,815) well supercedes that of the requests directed to us (1,744). Since our dependence on foreign special literature is so strong and postage expenses as well as lending expenses are steadily growing, it means a considerable burden on our hard currency budget. That is exactly why we cannot but appreciate the fact that 49 per cent of the mimeographed copies have been sent free of charge, especially from the FRG. We have interlibrary relations with 500 libraries in about 40 countries. This year the new departmental order re-regulating interlibrary lending has appeared. The growing economic difficulties have already affected international exchange, as a result of which the number of the publications obtained via exchange has been considerably diminished. For the moment the amount of the publications we supplied to other countries has been only slightly diminished. The Centre for Duplicate and Surplus Copies kept an approximate balance as to the items received and distributed. Of the approx. 24,000 volumes, 21,000 have been re-destributed to Hungarian libraries and about 3,000 volumes have been disposed of via exchange or via commerce. The holdings of the new storing library have been increased by 12,000 volumes. Research Activities. Computation Research activities have undergone further development regarding both the holdings of the library and our central services. As to the former one, case studies have been devoted to the construction of our future catalogue system, to the experiments with the catalogues based on new standards and to theoretical problems of restoration and preservation. As regards central services, the most important result was the integrated processing of the current Hungarian books. Preparations have been made as to the central card-supply and the introduction of CIP (Cataloguing 108
