My unpublished papers
I have several unpublished papers on Philpapers. I am told that:
  • This paper is flagged as a manuscript, but not a draft. Is it really a manuscript you don't intend to publish?
They are actually finished papers that I don't intend to publish. But when I look at the pull-down list for Publication Status I can't see a suitable option. What should I do?
