Initiatives that provide access to scientific physical collections of materials exist already in other disciplines, such as Geosciences, Microbiology, and Botanical Science, where collecting and archiving samples for further re-use is widely accepted as an important contribution to scientific work. Examples are the scientific collections of the U.S. Geological Survey 8 and the collections of drilling cores at the IODP (International Ocean Discovery Program) Core Repository . In chemistry, a few centers worldwide are making efforts to collect and store chemical substances for subsequent use. Exemplary well-known initiatives for the systematic collection of mostly commercial but also partly academic substances are the Compounds Australia 10 , EU-Openscreen , Chimiotheque National (ChemBioFrance) , and the Boston University Center for Molecular Discovery (BU-CMD) . The known initiatives collect and register the chemical substances for medical or pharmaceutical application purposes but, as far as we known, not for a general, open subsequent use of various kinds.
