Databases

Primary crystallographic databases

These are the major public databases of crystal structure and related data. They are generally maintained by large organisations and are valuable resources for the benefit of science as a whole.  
[logo] BCS: Bilbao Crystallographic Server of crystallographic symmetry information
[BMCD logo] BMCD: Biological Macromolecule Crystallization Database
[CRYSTMET logo] CRYSTMET: Metal and intermetallic structures
[CCDC logo] CSD: Cambridge Structural Database of organic and metal-organic structures
[ICSD logo] ICSD: Inorganic Structural Database
ICSD: Web interface to Inorganic Structural Database: ICSD-for-Web
[NDB logo] NDB: Nucleic Acid Database
[Pauling File logo] The Pauling File
[PDB logo] PDB: Protein Data Bank
[ICDD logo] PDF: Powder Diffraction File of the International Centre for Diffraction Data

Secondary crystallographic databases

These are academic or small-scale databases which are not maintained with the same level of longevity or security that is expected of the primary Databases.
