What do you call a person who actually writes books and articles doesnot get the credit for doing so?

There isn't one single perfect word to describe someone who writes books and articles but doesn't receive credit. However, depending on the context, several terms could apply:

* Ghostwriter: This is the most common and accurate term if the writer is intentionally uncredited. Ghostwriters are hired to write books, articles, or other materials for someone else who takes the public credit.

* Uncredited writer: This is a more general term that encompasses various situations where a writer's contribution goes unacknowledged, whether intentionally or unintentionally.

* Anonymous author: This applies if the writer chooses to remain anonymous, but it doesn't necessarily imply that someone else is taking credit.

* Shadow writer: Similar to ghostwriter, but often implies a more secretive or manipulative situation where the writer's lack of credit is exploitative.

The best term to use depends on the specific circumstances of the writer's lack of credit.
