Included, registered, available: let the preprint linking commence.

We began accepting preprints as a new content type last month (in a category known as “posted content” in our XML schema). Over 1,000 records have already been registered in the first few weeks since we launched the service.

By extending our existing services to preprints, we want to help make sure that:

  • links to these publications persist over time
  • they are connected to the full history of the shared research
  • the citation record is clear and up-to-date.

Preprints are go at Crossref!

We’re excited to say that we’ve finished the work on our infrastructure to allow members to register preprints. Want to know why we’re doing this? Jennifer Lin explains the rationale in detail in an earlier post, but in short we want to help make sure that:

  • links to these publications persist over time
  • they are connected to the full history of the shared research results
  • the citation record is clear and up-to-date

Doing so will help fully integrate preprint publications into the formal scholarly record.

Preprints and Crossref’s metadata services

We’re putting the final touches on the changes that will allow preprint publishers to register their metadata with Crossref and assign DOIs. These changes support Crossref’s CitedBy linking between the preprint and other scholarly publications (journal articles, books, conference proceedings). Full preprint support will be released over the next few weeks.

Getting ready to run with preprints, any day now

While preprints have been a formal part of scholarly communications for decades in certain communities, they have not been fully adopted to date across most disciplines or systems. That may be changing very soon and quite rapidly, as new initiatives come thick and fast from researchers, funders, and publishers alike. This flurry of activity points to the realization from these parties of preprints’ potential benefits:

Hello preprints, what’s your story?

The role of preprints

Crossref provides infrastructure services and therefore we support scholarly communications as it evolves over time. Today, preprints are increasingly discussed as a valuable part of the research story (beyond physics, math, and a small set of sub-disciplines). Preprints might play a positive role in catalyzing research discovery, establishing priority of discoveries and ideas, facilitating career advancement, and improving the culture of communication within the scholarly community.

Members will soon be able to assign Crossref DOIs to preprints

By August 2016, Crossref will enable its members to assign Crossref DOIs to preprints. Preprint DOIs will be assigned by the Crossref member responsible for the preprint and that DOI will be different from the DOI assigned by the publisher to the accepted manuscript and version of record. Crossref’s display guidelines, tools and APIs will be modified in order to enable researchers to easily identify and link to the best available version of a document (BAV). We are doing this in order to support the changing publishing models of our members and in order to clarify the scholarly citation record.


Why is this news? Well, to understand that you need to know a little Crossref history.

IOP has created an instance of the arXiv repository called at What’s the difference from arXiv? From the site - “We have focused on your experience as a user, and have addressed issues of navigation, searching, personalization and presentation, in order to enhance that experience. We have also introduced reference linking across the entire content, and enhanced searching on all key fields, including institutional address.”

The site looks very good and it’s interesting to see a publisher developing a service directly engaging with a repository.
