The more I read in this thread, the more I think that the Essential Guide to Characters / Who's Who in Star Trek approach would actually be more useful than a novelverse chronology in letting people know how many ongoing characters appear in the novels as well as getting them up to speed on major developments--it's less abstract and more personal, with illustrations of the characters (ideally) to make them "real" and give readers more of a reason to get invested in them (and literally invested in buying more novels
).
