Currently, if I want to add series information for a book in the item record when I link it, I would need to put it in the volume field. It'd be nice if there was an easy way to indicate if a book is part of a series and where it falls in the series without it creating a super long call number. Series info isn't standardized when it comes from publishers and isn't always included in the MARC record. This does make a difference for my patrons to know if a book is part of a series and would make it easier for staff too. I don't have a solid idea of how this would be implemented but it would be nice to have.
