Now What?

As you probably know, this year marks the centennial of the book The Road to Oz. As such, I've done blogs about the book and characters. Here's a list, with links:

The book itself
The Road to Oz - The Road Less Traveled?
John R. Neill - An Appreciation - Volume 1
Characters introduced in this book
The Shaggy Man
Button-Bright
Polychrome

Now that I've done those, and that the year isn't even halfway over, what should I do next? Possibly looks at the books that Baum crossed over with in this book?
