The Wonderful Wizard of Oz--L. Frank Baum

I read the original story by L. Frank Baum. I don't think I've read this since I was a kid, if even then. I thought it was reasonably good, though it, not surprisingly, had a dry explanatory tone that is common in older literature. Also, there's a lot of "As you know" dialogue. The scarecrow is constantly saying "I'm too dumb to do ____", and similar statements from the Tin Woodsman and the Lion. What interested me most were the differences I noticed.
SPOILER ALERT
SPOILER ALERT
(just in case anyone hasn't read this book from 1900!)

1. The ruby red slippers from the movie are actually silver. I suspect they made them red in the movie to show off their new color technology.
2. The Tin Woodsman is quite ruthless, beheading animals left and right, including a wildcat which was doing nothing more than chasing a field mouse. I'm sure they cut this to avoid blood.
3. The Lion is actually lion-shaped, not people shaped. Not a surprise there, since they had to have a guy in a lion costume.
4. The Emerald City is not really emerald. Everyone in the city must wear sunglasses by law that are locked onto your head, supposedly to protect you from being blinded by the dazzle. But the glasses are secretly tinted green, so everything looks green.
5. The Wicked Witch of the West does not use a crystal ball, she has just one eye which can see everything. Also, her skin is not green.
6. The Wizard takes on a different form for each of them--a giant head, a beautiful fairy, a ball of fire, and a 5-eyed 5-armed rhino-headed beast.
7. The Wizard gives them different gifts than the movie, though they are the same sort of "snake oil" placebo gifts.
8. It's not all a dream in the book.

Actually the ending is quite amusing. Dorothy's apparently been gone for quite some time, because Henry has had time to totally rebuild the house. Dorothy appears in the yard, Aunt Em finds her, and the first and only thing Em says is "Where did you come from?" That is a strange reaction for your dependent who has been missing for at least weeks, presumed dead in a tornado, that suddenly appears out of nowhere.
