A ready example is the ESV Study Bible, among others. I'm not sure what to do with a resource such as the NET Bible First Edition Notes, whether to conflate with the Study Bibles or give it a separate class e.g. Bible Notes.
I'm confused. I already have a type Study Bible with 52 resources. Are you saying that some study Bibles are in the wrong type? I also already have a type Bible Notes with 49 resources.
