Am wondering where or who one contacts to get permission to use a Neil Gaiman poem and excerpt from a website online interview in a book to be published early next year.

I contacted his publisher HarperCollins last May, but have heard nothing back from them.

Thanks for whoever can offer a suggestion, or even the exact details, on this.

Here are two useful addresses: Cat is a good general person to start off with, and his agent is Merrilee Heifetz.

Thanks for the info!
