On Rowling's website, she suggests sending fan mail to one of her two publishers in the U.S. or U.K. The publishing house serves as a middle man and forwards mail to the author. For best results, address your letter to J.K. Rowling, c/o Scholastic Inc., 557 Broadway, New York, NY 10012-3999. Rowling admits she can't answer questions or comment on ideas that you include in your letter. She's also unable to sign photographs or books, so if you send something to be autographed, expect to receive it back unsigned. And don't fantasize about gaining a pen pal; Rowling admits she's too busy with work and family commitments to take on a writing buddy.
