Hello,

I have been collecting autographs for a little while now, and would like to collect some first edition novels from Stephen King. I am wondering that the best way to go about proving their authenticity is. Is the ISBN code one way to do this? I have found a couple of books on Ebay and am hoping that someone will be able to tell me if they truly are first editions.

Thank you, and any help will be appreciated.
