When I expanded the LHMPodcast to a weekly schedule in August, I set up a rotating set of four monthly segments: On the Shelf (general discussion and listener questions), Author Interview, Author Book Appreciation, and the Historic Essay that I'd started out with. But four times a year, there's going to be a fifth Saturday in the month. For the moment, I'm planning to use those for some random surprise topics--something intentionally different from anything I do in the other segments. I also have some exciting long-term ideas that I may be ready to share soon.
