Taking a break, and a question for a librarian.

After the Varney fiasco, I'm taking a break before letting you guys pick my next book. LOL
However, I have a question for a librarian about adding books.
This one wasn't listed, even though I'm fairly certain I came across it here.
If it's a self published book, who do I put in as the Publisher if there's no publisher listed?
The author, or Amazon Digital Services LLC ?
