| 282068 (current) | 2023-03-26 | cod/ (saulius@tasmanijos-velnias) Adding the '_cod_related_entry_...' loop to those COD AMCSD entries that lacked it, and adding the related AMCSD database ID to this loop. | 1524087.cif | 
| 282053 | 2023-03-24 | cod/ (saulius@tasmanijos-velnias) Updating the existing COD records from the recent AMCSD downloads: - Adding AMCSD IDs to those COD records that exacly matched the AMCSD structures (comparing unit cells, space groups, coordinates and measurement conditions) but did not yet have the AMCSD ID; - Adding new mineral names, compound sources, measurement conditions (when those were missing) and other informations from the AMCSD CIFs. | 1524087.cif | 
| 176429 | 2016-02-13 | cif/ (antanas@kurmis) Replacing _cod_chemical_formula_sum_orig tag with _cod_original_formula_sum tag in multiple entries since the replaced tag is deprecated according to the COD CIF dictionary. | 1524087.cif | 
| 144751 | 2015-07-11 | cif/ Adding structures of 1524087 via cif-deposit CGI script. | 1524087.cif |
