Today's research includes watching: an A&E Biography that, incidentally, featured one of RS's magical illustrations; an episode of "Mutual of Omaha's Wild Kingdom," narrated by LG; and a feature from The History Channel.
Video/DVDs are especially useful for, say, notetaking on noises that animals make. Also, sometimes hearing (as opposed to reading) information triggers different kinds of ideas.
I also received an out-of-print, horridly written picture book that has some color photographs that will be useful for describing one of the major settings in the mss. I'll take a look at that later.
