As described in Can I add reviews for rejected or unpublished manuscripts?, Publons only displays reviews once a manuscript has been published.


We determine whether a manuscript has been published in one of three ways:

  1. Automated feeds from publishers
  2. The reviewer indicates that a manuscript has published
  3. We obtain the DOI for a manuscript

We periodically check for a DOI once we receive a review for up to 6 months. At that point, we assume the manuscript is unpublished. You are, of course, welcome to contact us at info@publons.com if a manuscript has been published and we missed it.
