This paper describes a GeoLibrary as metaphor-based information and navigation space to access geodata archives. Books, shelves and further library metaphors are used to present geo datasets. Additionally, a map is used to provide a familiar environment for spatial visualizations and navigation. From the technical point of view, GeoCrystal as innovative information visualization technique is embedded into a 3D information and navigation room of the Geo-Library to access geo datasets and geodata archives. GeoCrystal provides visualizations not only of search results, but is also useful for query formulation and query modification. Concerning semantic aspects, the structure of the GeoLibrary represents relationships among datasets and geodata archives. This structure is dynamically in the sense of user interests and individual objectives to access the wide range of information spectra of geodata disciplines respectively the individual way to dive into a semantic network for geodata. The paper is structured into three parts: Initially, chapter one and two introduce into the research topic of user guidance to geodata archives and provide a technical state-of-the art analysis within this context. Chapter three describes concepts and methods of the GeoLibrary and GeoCrystal. Finally, chapter four summarizes the most important results and discusses possible technical extensions as well as adoptions to other application fields.
