Crossref's newest member of the content family is preprints. At Crossref, preprints have custom support to make sure that, links to these publications persist over time, they are connected to the full history of the shared research results and the citation record is clear and up-to-date. But that's not the whole story, and we have three guest speakers lined up to share their thoughts and expertise on the role of preprints in research; Martyn Rittman from Preprints, operated by MDPI, Richard Sever from bioRxiv and Jessica Polka from ASAPbio.
