Richard, I see your point, but there could be many, many issues for each magazine, and over a hundred magazines total, so I don't want to make the users wade through a few thousand issues each time. I'd like to be able to drill down, first pick a magazine, then one of its issues.
What I'm thinking is do it backwards: give Magazine a ManyToManyField(Issue), and Issue a ManyToManyField(Article), so you create or select a Magazine, add an Issue, and then add Articles to it.
