II. The Use of the Library

are made up of international catalogue cards duplicated by the Ormig system.) The main catalogue comprises the alphabetical list of material acquired since 1950 as well as that of the old stock which is gradually being recatalogued. There is, in addition, a systematic catalogue arranged according to the Universal Decimal Classification (UDC), and a geographical catalogue in which the titles arc entered under the geographical subdivisions of UDC. There is also a series card catalogue to provide information for readers. Old material not so far recatalogued is listed alphabetically in a loose-leaf catalogue kept in big old boxes; some of its pages are manuscripts of former librarians. From the old system of shelving the books in an arrangement by broad subject fields, the Library has turned to the up-to-date current number or accession order of shelving. Leaving the Catalogue Room, we enter the sunlit Reading Room facing the Danube embankment (Fig. 12). From its windows there is a splendid view of Gellért llill, the Chain Bridge and the Castle of Buda. On one wall of the room marble tablets remind the visitor of the donors who have enriched the Library with their endowments, while on the other, three oil paintings show Ferenc Kölcsey, an outstanding Hungarian poet and philosopher, the author of our national anthem; János Batsányi, a poet who greeted the French Revolution; and Farkas Bolyai, a noted scientist, father of the world-famed matematician János Bolyai. A reference library of 3000 volumes is located here in bookcases along the walls, arranged by subject fields to which readers have free access. 34 research workers can be accommodated in this room. The next door opens into the Periodicals Reading Room. It has a shelving of current issues of about 1300 periodicals of the approximately 4000 serial titles (journals, annals, yearbooks, reports, etc.) received. 8 research workers can be accommodated in this room. Bot h the alphabetical and subject catalogues of the periodicals are housed here (Fig. 13). The full stock of periodicals comprising some 10 000 kinds of publication in about 100 000 volumes, is located in the new periodicals stack of the Library that was constructed after the Liberation, and is equipped with modern adjustable iron shelves (Fig. 14). The Library issues lists of current periodicals received from abroad. The periodicals group became a separate division in 1954. 2 17
