Crossref metadata for preprints: Discussions and recommendations

In 2016, Crossref launched a metadata schema for ‘posted content’ with the aim of better accommodating the metadata needs for preprints, working papers, theses, reports, and related outputs, which are not typically peer-reviewed. In 2021, Crossref formed an Advisory Group (AG) to discuss how the quality of metadata for preprints using this schema could be improved.
