Cambridge Structural Database System

CSD is a repository for small-molecule organic and metal-organic crystal structures compiled from the published literature and directly deposited data. It is maintained by the Cambridge Crystallographic Data Centre. As of 2018, it contained more than 918,000 entries obtained from x-ray and neutron diffraction.  Approximately 50,000 new entries are added each year.
CSD is installed on a workstation on the first floor in the Engineering & Science Library. A second copy is available in the Chemistry Department in Chernoff Hall.
