Fill out the conversations

For all the scholars, you can see the other scholars with whom they are in conversation, where "in conversation" means that they are cited in the same context, either paragraphs of the appendix or the commentary notes. You could pick a commentary note with a lot of conversations in it, create a group, and add those scholars as items to the group. Then, members of the group could read further about the cited sources and expand on the conversations, for example, by explaining how some of the different perspectives or conclusions derive from their theoretical approaches.
