Printing | Field 753 prints as a heading and a tracing. It prints in uppercase and lowercase as entered or as determined by your profile for 7xx fields. The print program supplies a dash (--) between data in each subfield and a period at the end of the added entry or tracing, unless final punctuation (. ! ?) is present. The heading sorts into the same receiving catalog as field 710 (Added Entry–Corporate Name). Multiple tracings print in order of appearance in the record. | ||||||||||||||||||||
