In longman Dictionary Of Contemporary English, the word "AUTHOR" being used as a "VERB" was defined as follows:
Author: to be the writer of a book, report etc.
I think the definition is completely wrong, since the definition defines it as if it is a noun.
I think a better definition for the word as a "VERB" is the following:
Author (V): to write a book, article, etc.*
