Zmiany w zasadach realizacji zadań w Bibliotece Głównej Uniwersytetu Ekonomicznego we Wrocławiu w latach 1947–2016

The article presents changes which have taken place in the principles of realization of tasks of the library within the years 1947–2016. The most important tasks of a scientific library are: the organization of bibliographic and information workshops, didactics and scientific research activities. The fulfilling of certain tasks in five following periods of the library’s existence has been analyzed based on publications of the library staff. The tasks themselves have not been changed, what has been altered, are the methods and tools of their realization. The conclusion points at the causes of change: the law, needs of users, modification of didactic programs, locum conditions, development of IT technologies and the commitment of librarians.
