The library-network of the Hungarian Academy of Sciences
49 special literature is concerned, all these are the tasks of scientific information. It is a matter of organization that this task is carried out by a single but adequately strengthened library or by a collaboration of a librarv and a documentation section. The most important traditional tool of making documents available is the library catalogue. In the Academy's institutes alphabetical and subject catalogues help the reader. The selection of the appropriate system of classification is far from easy: however the advantages of the UDC, which is widely adopted in Hungary, and first of all its international character generally convince its opponents. However, the usual catalogue system of big libraries may not be sufficient for a research libray which takes its information function seriously. What the painstaking information work requires is a thorough analysis of the content of documents. The difficulties of the analytical work in research libraries is increased considerably by the great variety of types of documents collected by them. Thus a new form of content analysis, that is a system of classification should be worked out, which would help the reader find the necessary material easily. Attempts have been and are being made to elaborate a multi-dimensional analysis of certain types of documents. Several research libraries are making experiments with marginal punched cards. According to the experiences gained in this work, marginal punched cards seem to be sufficient to meet the information needs of research workers, at least in a well-defined, specialized branch of science. Library and documentation. A characteristic feature of the development of Hungárián library system is that, as a rule, documentation did not become detached from the library to form a separate section, but the documentation centres are based and are relying on libraries. Owing to the historical development of Hungárián scientific life, institutes of long standing and tradition are mostly functioning in the field of social sciences. Although the libraries of these institutions hold higly valuable collections, containing old books for the most part, they could not tackle the emerging tasks of bibliographical information and documentation due to the lower rate of their development, lack of organization and personnel. Thus was it that bibliographical work in the institutes was started separated from their respective library. This kind of information was initiated in social science institutes and has, by and large, succeeded in meeting the needs of research work. As is known, the most important basis of social science investigations is förmed by written sources, books, periodicals, while the different forms of rapid information services are less important in these 7
