An excerpt from the website Who's Who and What's What in the World of Dr. Seuss
I love words and dictionaries, so this site is my very favorite. It's the official dictionary of places you'll go, creatures you'll meet, things you'll see, and weird words you can find in the books of Dr. Seuss, for example, under the letter "W" you encounter everything from waggy bears to wuzzled wheat. What a treat!
And I also recommend:
The Amazing World of Dr. Seuss Museum
Yes, this museum is a real place. It's located in Dr. Seuss' home town of Springfield, Massachusetts. If you’re lucky enough to visit, you’ll find a replica of his studio, complete with original art materials, family photos, letters, and the stuffed dog, Theophrastus, that his mother gave him when he was a boy.
Like the great doctor, this site slyly teaches kids to read while they're having fun. There are animated games, activities, and information, all about Dr. Seuss and his books.
