The Crystallography Open Database (COD) is a database of crystal structures. Unlike similar crystallography databases the database is entirely open-access with registered users able to contribute published and unpublished structures of small molecules and small to medium sized unit cell crystals to the database. As of March 2014 the database has more than 270000 entries. The database has various contributors and contains CIFs as defined by the IUCr.
