Preprint advisory group

The purpose of the preprint Advisory Group is to support Crossref to collect and improve the quality of metadata for preprints. The group is comprised of both our members as well as non-members (third party platforms and organizations) who are interested in preprints.

How the group works (and the guidelines)

The preprint Advisory Group is led by a Chair and a Crossref Facilitator, who together help to develop meeting agendas, lead discussions, outline group actions and rally the community outside of the Advisory Group for support with the service where appropriate.

The group is currently active. Please contact Martyn Rittman with any questions.


Over its first year of operation, the Advisory Group has developed recommendations in four key areas of preprint metadata. These are:

  • preprint withdrawal and removal
  • preprints as an article type
  • versioning of preprints
  • preprint relationship metadata.

In July 2022, the AG published a set of recommendations ( and invited public comment, available on our Community Forum. An in-depth report of discussions of the AG is available at


Minutes of the group are available on this page.
