Books that authors did not want published.

I recently read The Castle by Franz Kafka, a book that he considered a failure and chose not to publish but was released posthumously. I’ve also read The Red Book, Carl Jung’s personal diary wish he also did not want to be seen until long after his death. I am interested to know if there are any other books that fit that genre. Books that well known famous writers/ thinkers did not want to be seen by the public but came out anyway after their death. Embarrassments, failed projects, etc.
