176808 (current)	2016-02-21	cif/1/ (antanas@kurmis) Updating the values of the '_citation_journal_id_ASTM' data item for multiple entries in range 1. The tag values contained the full citation information (sometimes for multiple citation sources) instead of only the CODEN code. The data item was either split into corresponding data items and placed in a loop or removed (if the citation corresponded to the original publication that was already defined with the _publ_* and _journal_* tags). The bibliography was also updated for some entries.	1514227.cif
