Thanks again for your reply. If you search the iBookstore from within iBooks for my book "Sodium" (its a sci-fi novel), then click on the book icon, you will see in the middle of the page a link for "View Author Page". If you click on the link it says "Device Not Supported" or something to that affect. So, I was wondering if there was a way for me to link that to my home site so that if someone wanted to read more about the author or if I have any other books, they would be taken to my site. This "View Author Page" link does not show in the iTunes browser window when searching for my book so that may be where you missed it. It only appears when searching through the iBookstore from iBooks on my iPhone or iPad.
My guess is that either its something they sell to publishers as an extra or maybe it needs to be embeded in the metadata of the epub format. I published through lulu.com and they said they could not link it so I was wondering why its there.
