What’s the difference between a ghostwriter and a co-writer?

[michaeljohnson]

The main difference between a ghostwriter and a co-writer is authorship. A ghostwriter writes the entire book on behalf of the author but remains anonymous, with the author receiving full credit. In contrast, a co-writer collaborates with the primary author, and both are credited as authors of the book. Ghostwriters are often hired when the primary author prefers to stay out of the writing process, while co-writers share the creative responsibility. Both roles aim to produce a professional book, but the credit and process differ significantly. https://spineauthors.com/
