I'm not sure if you can hold multiple accounts. I believe you should contact the support, and if it is possible they will do that. In the meantime the Librarians can help in moving the books in the correct accounts, if you provide us with all the names and books published under those names.
Regarding author pseudonyms or pen names - some authors write or have written under multiple names. When editing or adding information for a book written by an author with multiple names, enter the author's name as on the front cover as the primary author. The author's other names may be added in the other author fields.
At the moment you will have semi-Librarians status only for your current profile.
P.S. The books should be under the pseudonym they are published. Additionally your most commonly/real name can be added as a second author, or all other names can be listed in the descriptions of all the profiles you have.
Edit: Please don't add King in the "role" field, as it is not a role, if you have such pseudonym add it in the second field.
