The article is about the chance of getting acquainted with the best practices of operating the Danish library system in the course of a study visit. During the trip different types of libraries have been visited. It was a good opportunity to gain experiences, to compare them and search analogous features with the Hungarian library systems. Some elements worth following have been identified: high-quality central services with access from anywhere, good adaptation to local features, practically completely free services, and the extreme importance of providing a good infrastructure for educational, cultural and social activities. The differences in social, economic and cultural backgrounds must, however, be always considered, as models cannot be adopted without any changes but should be adjusted to the specific environment.
