Done and done.
I did find this email for Random House -
ecustomerservice@randomhouse.com - which I used instead of the form on their site, hope that's ok.
As for Bradbury, his books are never going to be published in electronic format, IMO. At ComicCon he said that he wanted to destroy the internet!

It was great hearing him talk (I even ran into him out in the hall!) but man, is he set in his ways!
