The Museum's collections include millions of specimens, and their size and quality place the Museum among the best in the world. The collections provide the basis for the research carried out in the scientific departments, and, through loans and visits by guest researchers, are constantly used by scientists and institutions throughout the world. It is a crucial role of the Museum to keep these collections available for international research, and to preserve them for future generations. Parts of the collections, presented on the Museum's web pages, are also registered in searchable databases.
