Here are some other terms you might hear:
* Unpublished work: This is a general term that can refer to any work that has not been published, including books, articles, poems, etc.
* Draft: This term is used for a work in progress that is not yet finished.
* Self-published manuscript: This refers to a book that the author has chosen to publish themselves, without going through a traditional publishing house.
It's important to note that even though a book is not published, it can still be valuable. It can be a valuable resource for the author, a potential source of income, and a way to share their ideas with the world.
