Sorry--I couldn't find Wynken, Blynken & Nod. I have that book, and I can't tell you how precious it is to me. I think it was the illustrations more than the stories and poems, because they inspired my imagination and sense of beauty.
I've never read 'Wild Things', but I've seen it. I'm guessing its popularity has more to do with how strongly kids identify with it and how deeply it inspires their imaginations. I've read some beautifully written books that have left me completely cold. Even some that I've enjoyed don't linger in my memory and heart the way a book that makes me feel part of the story lingers.
