The cooperation between the Nordic parliamentary libraries started in 1922. From 1965 and onwards meetings between the Parliamentary Librarians have been held every year. The meetings are organised in turn by one of the parliamentary libraries. Topics discussed are strategic and organisational issues and technical and more practical issues. The aim is to share knowledge and best practice on all levels of library business. The staff have their meeting or study tour once every other year. The cooperation is based on an open and inclusive network for libraries within similar parliamentary traditions.
