One main idea when developing user interfaces for digital and hybrid libraries is to make use of real-world metaphors. This gives library customers the advantage to access digital collections the same way as they would traditional collections. However, while existing “real world” library interfaces still miss the attraction of the wider public, game industry is very successful selling virtual reality games. In this paper we describe a study how to close the gap between these two worlds. We describe the development of a library interface that bases on a commercial computer game. The interface models the interior and exterior of an existing library building including the most important functions for literature search. Not only teenagers tested the developed prototype with big attention.
