Associations of special libraries in Hungary are being developed to provide universal availability of published works on a national and international level. While most library legislation recognizes considerations, concerns of document security, copyright, reprography and computerized services are also matters of legislative importance, particularly for special libraries. Hungarian law treats all libraries as a unified system with individual libraries in four administrative networks--public, school, academic, or special. A central library in each network provides professional operational supervision, procedural methodology, and professional training. Libraries within these networks are encouraged to form associations based on professional disciplinary interest, e.g., chemistry, geology, telecommunications. Each professional association of libraries involves one central library and other cooperating libraries. Among the tasks of the associations are maintenance of statistical information, compilation of library holdings, evaluation against international holdings, interlibrary cooperation, and provisions for reproduction and dissemination of library materials. On the international level, these associations are encouraged to develop bilateral affiliations for exchange of publications and interlibrary loan. (RAA)
