Translation guide
The English word "unpublished" refers to something that has not been made publicly available, typically a written work, data, or information. In Japanese, the most natural way to express this depends on the context: whether it's a book, article, report, data, or a general state of not being released.
Describing a book, article, manuscript, or other work that has not been published or released to the public.
The most common and versatile term for 'unpublished', used for research, manuscripts, data, etc. It literally means 'not yet announced/presented'.

未発表 (mihappyō) is the most general term for 'unpublished' and implies something has not been formally presented or announced. 未公開 (mikōkai) means 'not yet made public' and is often used for things like films or events. 非公開 (hikōkai) means 'not open to the public' and implies intentional confidentiality or restricted access.
While 出版する means 'to publish', the negative form 出版していない is not always the most natural way to say 'unpublished'. Use 未発表 or 未刊 for attributive use, and 出版されていない only when you need a full clause.
