And I will refer you back to my original question's title, where I wrote
I'd really need access to his KDP account (but) I know that can't be done,. I don't know how much more clearly I can put it.
Let me reframe the question.
Let's say, for argument's sake, you're a
digital publisher with
several titles by different writers available through Amazon.
You want to expand the range of books you publish, but in order to do so, you need more hands on deck. The days of being a one-man show are fast evaporating as you expand and grow. Most especially, you need a person expert in metadata and maybe also another expert in marketing.
However, the books you publish are, at least for the moment, published only through your single KDP account. In the long term, that's less than optimal, since your metadata expert won't legally be able to access those books and work on them directly without risking the account being shut down. You know this, I know this.
So you do some research and discover that there is such a thing as an Amazon publisher account. I found the following article after I posted my original question:
https://kindlepreneur.com/how-to-start-a-publishing-company/. Apparently, all this gives you a
second KDP account through which to upload ebooks.
You search online for information about such accounts and how they work. What you want to know is whether or not a publisher's account offers the ability to allow, say, an employee, intern, contractor or such the ability to access the metadata associated with each of the company's publications so you, meanwhile, can get on with the business of editing.
The only problem is searching on such things returns a vast amount of information related only to single self-publishers publishing nobody's books but their own.
The person most likely to be able to answer my question, I suspect, is someone who now runs a digital press or something like that. It may be the answer is simply 'no'. That would be sufficient, if disappointing.
Again, I am
not talking about handing details of a single user's account to someone else. That is against Amazon's rules, as I've said from the start I'm aware.
