MARC 581 Publications About Described Materials Note
MARC field 581 in the Bibliographic record contains a citation or other information about a publication that is based on the use, study, or analysis of the materials described in the record. It is repeatable. It's not currently (Aug. 2015) possible to indicate through coding that the note only applies to a particular copy, or a particular institution.
For informal electronic publications like Folgerpedia and The Collation, make a MARC 856 Electronic Location and Access note instead.
MARC field Tag in the Formatname format contains [text]. This field is repeatable.
