The CSD records bibliographic, chemical and crystallographic information for small organic molecules and metal-organic compounds. WebCSD has a built-in editor for structure/similarity searching, plus JMol and AstexViewer.  Because this is a Java application, it may run slow at the beginning of your session. If you continue to have problems with Web CSD running too slowly, please refer to the FAQ page for possible solutions. WebCSD is not a complete substitute for the locally installed version of the database that UCSC researchers can download from the CSD page at UCLA. Power users should consider downloading and installing CSD on their own computers.
