There are two ways you can do this, either
- add your review through the post-publication review forms. Some pre-print servers mint DOIs for their publications, if not you can add the paper by its title and then contact us to link it to the correct paper.
- import the publication by it's unique identifier (e.g. a DOI or arXiv ID) through the search bar at the top of each Publons page, then click "Post-publication review".
We are still working on improving these workflows so if you have any feedback, please let us know!
