Our members asked for the flexibility to register content at different points in the publishing lifecycle, so we extended our infrastructure to support members who want to register preprints.
Our custom support for preprints ensures that links to these publications persist over time; that they are connected to the full history of the shared research results; and that the citation record is clear and up-to-date.
We have designed a schema together with a working group that included preprint advisors bioRxiv and arXiv, along with some members including PLOS, Elsevier, AIP, IOP, ACM. The schema lays out what metadata is specifically important for preprint content. We also developed a notification feature to alert preprint creators of any matches with journal articles, so they can link to future versions from the preprint.
It’s important to clearly label the content as a preprint using a preprint-specific schema. It’s not advisable to register preprints as data, components, articles, or anything else, because a preprint is not any of those things. Our service allows you to ensure the relationships between preprints and any eventual article are asserted in the metadata, and accurately readable by both humans and machines.
Since November 2016, members have been registering tens of thousands of preprints with us, and thousands of those in turn already have matches with journals articles too (requires a JSON viewer). These relationships in the Crossref metadata, available through our APIs, are relied apon by many parties–from researchers to funders–to discover, track and evaluate the preprint journey.
Our custom support for preprints offers:
Members depositing preprints need to make sure they:
Preprint creators who would like to use our preprint service should apply to join as a member (annual fee starting at $275). Membership of Crossref can be layered, you could join directly, or under a Sponsoring Member who handles your technical and/or financial administration. We have a dedicated fee structure for registering each preprint and volume discounts offered for both backfile and current content. Please see our fees page for more information.
Are you an existing Crossref member who wants to assign preprint DOIs? Let’s talk about getting started or migrating any existing mis-labelled content over to the dedicated preprint deposit schema. You can also give us a specific contact who will receive match notifications that a manuscript/version of record (AM/VOR) has been registered. If you’re not yet a member but want to register your preprints so they are included within Crossref infrastructure service, please contact our membership team so we can answer any questions and get you set up.
