The inorganic crystal structure data base

An inorganic crystal structure data base is described which will, when completed in the next year, contain details of all the 23 OOO published structum of inorganic crystals. This pper describes the structure of the data base, the procedures used to check the data as they are entered, and the program used to access them. Plans for the future development of the data base system include defining search keys on the basis of bonding topologies and crystal structure types as well as plans for providing an integrated crystal structure retrieval system.
