| 202017 | 2017-10-14 | cif/ Marking COD entries in range 7 that are known to be related to ChemSpider entries using the _cod_related_entry data loop. |
7106520.cif |
| 180169 | 2016-03-26 | cif/7/10/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in subrange 7/10/65. |
7106520.cif |
| 106664 | 2014-03-15 | cif/ (saulius@koala.ibt.lt) Adding DOIs to the rest of the Chem. Comm. files. Some of these files have author names differing from PubMed in diacritics (either diacritics are omitted or we have encoding problems); or they have a year difference of 1. However, since first pages always match and author names are variants of each other, I assume that DOIs are assigned correctly. |
