Where can I get more molecule co-ordinate files?

In addition to the three example files that are distributed with RasMol, the protein crambin (1crn.pdb), the DNA-binding protein CRO (3cro.pdb) and aspirin (asprin.alc), the major source of data files for RasMol is the Protein Databank at Brookhaven National Labs.
