AUTHOR UNKNOWN BYLINE is a term used to describe a piece of writing that does not have an author's name attached to it. The acronym ANON, which stands for 'ANONYMOUS, ' is often used as a shorthand way of referring to this type of writing. This type of writing can be found in many different forms, including newspaper articles, blog posts, and even books. It is often used when the author wishes to remain ANONYMOUS or when the author is unknown.
