The controversy regarding library science as a separate branch of science in Poland is reviewed. In People's Poland, work in the field of library science has adopted the features of collective research. This is due to the unprecedented increase in the number of libraries, book collections and readers as well as changes in the methods of examining social phenomena. The place of individually active specialists in the management of libraries has been taken by scientific institutions set up for this purpose. In addition to university departments, work in the field of library science is also conducted in scientific libraries of institutions of higher learning, the Polish Academy of Sciences, and in larger public libraries. The initiator of various types of research work related to current organizational problems of librarianship is the Polish Library Association. Librarianship requires systematic studies on its theoretical foundations, practical skill in conducting research and didactic activity, i.e., to disseminate and popularize among the younger generation everything that is progressive. The setting apart of library science from the group of other disciplines can take place only by means of intensive research in this undoubtedly difficult, but most fascinating field of social life.
