PUBL_018,PUBL_019, PUBL_020,PUBL_021	`_publ_contact_author_name _publ_contact_author_address`	This test has failed due to what is probably an incorrectly formatted author/address loop. Usual errors encountered in this loop are due to an incorrect number of elements being given in the loop, or misuse of ; (semi-colon) delimiters in order to get the CIF to pass checkCIF. If there are no footnotes to be included in the author/address loop then the loop should have the form as below, loop_ _publ_author_name _publ_author_address 'Bowes, Katharine F.' # Format is 'Surname, Firstnames' ; School of Chemistry University of St Andrews St Andrews Fife KY16 9ST Scotland ; 'Ferguson, George' ; Department of Chemistry University of Guelph Guelph Ontario Canada N1G 2W1 ; When footnotes are required, then the format is as below.

PUBL_024	`Large number of authors.`	The number of authors is greater than 6. Please specify the role of each of the co-authors for your paper.
