AMCSD is an interface to a crystal structure database that includes every structure published in the American Mineralogist, The Canadian Mineralogist, European Journal of Mineralogy and Physics and Chemistry of Minerals, as well as selected datasets from other journals. The database is maintained under the care of the Mineralogical Society of America and the Mineralogical Association of Canada, and financed by the National Science Foundation. You may search by a mineral of your choice, or choose a mineral from a complete list to help aid your research.
The Crystallography Open Database (COD) is a sister to the American Mineralogist Crystal Structure Database. COD contains all the data that is in AMCSD as well as data that has been deposited by individuals and laboratories. It offers a different interface for the search and retrieval of data.
