It seems that blogs are always linking to other blogs, who link to other blogs, etc. which could leave you surfing the internet for the rest of your life. But I'm just going offer two blogs from authors that I enjoy:
Douglas Florian: The staff here in the children's room just saw Douglas Florian speak at a breakfast meeting and he was wonderful. He read his poems aloud and had us all laughing out loud. I'm also making a resolution to try to read more poetry and he posts a lot of poetry on his blog.
Mo Willems : I don't think there's a funnier children's author out there, because it seems like he mostly wants to make kids laugh and if the parents get the joke too, it's just a bonus. So click away and find out where he'll be appearing (be prepared to be charmed if you see him speak) and get a peek at some awesome fan mail.
