My biggest library is full of RPG material. Many of these books have supplementary files (web enhancements, errata documents, FAQs, etc.).

My technical library is similar: Python book has one or more related code decks, and so on.

Conceivably I could have multiple editions of the same book.

Is there a good way to associate two titles? The first option that comes to mind is a tag field for this purpose. Part of me thinks I want an explicit "this title is connected to that one", but I suppose a tag that says these titles are connected somehow will be sufficient.

(IOW, I see a way to do it, I wonder if there's another way.)
