  Cambridge Structural Database (CSD) - The world's repository of small molecule experimental crystal structures
    The Cambridge Structural Database (CSD) is distributed as part of the CSD System which includes software for:

• search and information retrieval (ConQuest)
• structure visualisation (Mercury)
• numerical analysis (Vista)
• intermolecular interactions (IsoStar)
• molecular geometry (Mogul)
• database creation (PreQuest)
IsoStar contains data derived from both the CSD and the PDB.

SuperStar - Predicting Protein-Ligand Interactions Using Experimental Data
    SuperStar is a program for generating maps of interaction sites in proteins or around small molecules using experimental information about intermolecular interactions. The interaction maps that SuperStar generates are therefore fully knowledge-based.
