Thanks for that clarification. I have some technical writings I thought might be good to post, but haven’t.
Can an author link to video (my own youtube videos, for example) in books posted to Amazon? I heard Amazon jealously guards its link structure to keep revenue and customers inside their architecture. But it sounds like a great opportunity as well.
Yes, in fact links in e-books are quite common. Amazon is restrictive in not letting you link to a competitor (for example a link to Barnes and Noble or to Walmart), but links to author websites, youtube, google docs, etc. are all common.
In my e-books, I link to my website, my e-mail list sign up, and other books on Amazon.
