Our library is beginning to create MARC Holding records for all materials, including monographs. When we purchased the software segment to do this, our vendor told us that we could tie together bibliographic records for bound-withs and analytics by repeating the 004 control field. But the MARC documentation for Holdings Data says that the 004 field is not repeatable. If anyone can give me some ideas for dealing with these bound-withs without going against the MARC standard, I would appreciate it very much.
