The legal status of libraries in Poland was defined by the decree on libraries and the care of collections dated 17 September 1946. This decree was repealed by the Act on libraries, dated April 9, 1968, which was repealed by Article. 31 of Act on libraries, dated 27 June, 1997. The legislature didn’t define the concept of a library, but only pointed out the basic tasks of the library. Not every entity that uses its name in code “library” is a library within the meaning of the Act. Public libraries can’t be combined with other institutions, school libraries or pedagogical libraries. The Act regulates the notion of library materials, the National Resource Library, the competence of the Council for this resource, the tasks and functions of the National Library Council. The problem is in the library policy, which hasn’t been defined in the an appropriate manner. In addition to public libraries, there are scientific, school and pedagogical libraries. The law doesn’t regulate the status of library staff. The important role of libraries show numerous provisions of the Constitution
