Shelf Raiders: Program Ideas from the Nonfiction Section

I thought it would be interesting to see if we could all come up with a list of ideas for programs based on Dewey classes. I know poor DDC has fallen out of favor, and I'm hardly its biggest defender myself, but using its structure could lead to some great ideas for programs for all ages (not limiting this to kids). Let's give it a shot:
