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.

New Crossref DOI display guidelines are on the way

TL;DR Crossref will be updating its DOI Display Guidelines within the next couple of weeks. This is a big deal. We last made a change in 2011 so it’s not something that happens often or that we take lightly. In short, the changes are to drop “dx” from DOI links and to use “https:” rather than “http:”. An example of the new best practice in displaying a Crossref DOI link is: https://doi.

Outreach Day DC. Next Up? You Tell Us

Rallying the community is a key Crossref role. Sometimes this means collaborating on new initiatives but it is also an ongoing process, a cornerstone of our outreach efforts. Part of rallying the community is bringing people together, literally, in a series of outreach days around the globe. It means we encourage dialog with us and among publisher members and non-publisher affiliates. We want to hear from the community and we hope to facilitate conversations in it. Not just about Crossref, but larger issues of scholarly communications and your particular part in it. The Crossref outreach team is doing a number of events around the world to bring together the community for updates, feedback and discussion.

Linked Clinical Trials initiative gathers momentum

We now have linked clinical trials deposits coming in from five publishers: BioMedCentral, BMJ, Elsevier, National Institute for Health Research and PLOS. It’s still a relatively small pool of metadata - around 4000 DOIs with associated clinical trial numbers - but we’re delighted to see that “threads” of publications are already starting to form. If you look at this article in The Lancet and click on the Crossmark button you will see that in the Clinical Trials section there are links to three other articles reporting on the same trial: two from the American Heart Journal and one from BMJ’s Heart.

Where do DOI clicks come from?

As part of our Event Data work we’ve been investigating where DOI resolutions come from. A resolution could be someone clicking a DOI hyperlink, or a search engine spider gathering data or a publisher’s system performing its duties. Our server logs tell us every time a DOI was resolved and, if it was by someone using a web browser, which website they were on when they clicked the DOI. This is called a referral.

This information is interesting because it shows not only where DOI hyperlinks are found across the web, but also when they are actually followed. This data allows us a glimpse into scholarly citation beyond references in traditional literature.

Getting Started with Crossref DOIs, courtesy of Scholastica

_I had a great chat with Danielle Padula of Scholastica, a journals _platform with an integrated peer-review process that was founded in 2011. We talked about how journals get started with Crossref, and she turned our conversation into a blog post that describes the steps to begin registering content and depositing metadata with us. Since the result is a really useful description of our new member on-boarding process, I want to share it with you here as well.

The Wikipedia Library: A Partnership of Wikipedia and Publishers to Enhance Research and Discovery

Back in 2014, Geoffrey Bilder blogged about the kick-off of an initiative between Crossref and Wikimedia to better integrate scholarly literature into the world’s largest knowledge space, Wikipedia. Since then, Crossref has been working to coordinate activities with Wikimedia: Joe Wass has worked with them to create a live stream of content being cited in Wikipedia; and we’re including Wikipedia in Event Data, a new service to launch later this year. In that time, we’ve also seen Wikipedia importance grow in terms of the volume of DOI referrals.

How can we keep this momentum going and continue to improve the way we link Wikipedia articles with the formal literature? We invited Alex Stinson, a project manager at The Wikipedia Library (and one of our first guest bloggers) to explain more:

Linking clinical trials = enriched metadata and increased transparency

****We will shortly be adding a new feature to Crossmark. In a section called “Clinical Trials” we will be using new metadata fields to link together all of the publications we know about that reference a particular clinical trial.

Most medical journals make clinical trial registration a prerequisite for publication. Trials should be registered with one of the fifteen WHO-approved public trial registries, or with clinicaltrials.gov, which is run by the US National Library of Medicine. Once registered, a trial is assigned a clinical trial number (CTN) which is subsequently used to identify that trial in any publications that report on it.

Crossref & the Art of Cartography: an Open Map for Scholarly Communications

 

In the 2015 Crossref Annual Meeting, I introduced a metaphor for the work that we do at Crossref. I re-present it here for broader discussion as this narrative continues to play a guiding role in the development of products and services this year.

Metadata enable connections

Cartography BorgesAt Crossref, we make content easy to find, link, cite, and assess through DOIs. Publishers register their publications and deposit metadata through a variety of channels (XML, CSV, PDF, manual entry), which we process and transform into Crossref XML for inclusion into our corpus. This data infrastructure which makes possible scholarly communications without restrictions on publisher, subject area, geography, etc. is far more than a reference list, index or directory.

The logo has landed

Crossref_Logo_Stacked_RGB_SMALLThe rebranding of Crossref was top priority when I joined in May in a new role called “Director of Member & Community Outreach”. Since then I’ve been working to understand the array of services, attributes, and audiences we have developed; to answer the questions “What do we do, for whom, and why?”

As Crossref prepares to celebrate turning fifteen at our annual meeting next week, I am thrilled to present our new brand identity with key messages and logo. And along with “thrilled” you may also detect “nervous excitement”.
