Sheryl asked me to share some research tips. Hahahaha! I haven't done research in years! So, I'm pretty much winging it. If I figure anything out, I'll let you know, though.
I just went to the library and typed in the subjects I wanted. Then when I couldn't find them, I talked to the reference librarian who helped me out.
I ended up with a great source there to look at and some to bring home. She also showed me how to access their articles on-line so I can do that at home.
Finding pictures of my characters was Angela Hunt's idea, not mine. But it does help me a lot to be able to see them!
