The integrity of the scholarly record is an essential aspect of research integrity. Every initiative and service that we have launched since our founding has been focused on documenting and clarifying the scholarly record in an open, machine-actionable and scalable form. All of this has been done to make it easier for the community to assess the trustworthiness of scholarly outputs. Now that the scholarly record itself has evolved beyond the published outputs at the end of the research process – to include both the elements of that process and its aftermath – preserving its integrity poses new challenges that we strive to meet.
I’m pleased to share the 2022 board election slate. Crossref’s Nominating Committee received 40 submissions from members worldwide to fill five open board seats.
We maintain a balance of eight large member seats and eight small member seats. A member’s size is determined based on the membership fee tier they pay. We look at how our total revenue is generated across the membership tiers and split it down the middle. Like last year, about half of our revenue came from members in the tiers $0 - $1,650, and the other half came from members in tiers $3,900 - $50,000.
Our entire community – members, metadata users, service providers, community organizations and researchers – create and/or use DOIs in some way so making them more accessible is a worthy and overdue effort.
For the first time in five years and only the second time ever, we are recommending some changes to our DOI display guidelines (the changes aren’t really for display but more on that below). We don’t take such changes lightly, because we know it means updating established workflows.
I’m delighted to say that Martin Paul Eve will be joining Crossref as a Principal R&D Developer starting in January 2023.
As a Professor of Literature, Technology, and Publishing at Birkbeck, University of London- Martin has always worked on issues relating to metadata and scholarly infrastructure. In joining the Crossref R&D group, Martin can focus full-time on helping us design and build a new generation of services and tools to help the research community navigate and make sense of the scholarly record.
Cited-by gives our members full access to citations, helping them to build a picture of how research has been received by the community.
Scholars use citations to critique and build on existing research, acknowledging the contributions of others. Members can include references in their metadata deposits which Crossref uses to create links between works that cite each other. The number of citations each work receives is visible to anyone through our public APIs. Through our Cited-by service, members who deposit reference metadata can retrieve everything they need to display citations on their website.
Members who use this service are helping readers to:
easily navigate to related research,
see how the work has been received by the wider community,
explore how ideas evolve over time by highlighting connections between works.
Watch the introductory Cited-by animation in your language:
Cited-by begins with depositing references as part of the metadata records for your content. Learn more about depositing references.
A member registers content for a work, the citing paper. This metadata deposit includes the reference list. Crossref automatically checks these references for matches to other registered content. If this is successful, a citation is created.
Crossref logs the citations and updates the citation counts for each work. You can retrieve citation counts through our public APIs. Members who deposit references can sign up for the Cited-by service to retrieve the full list of citing works (not just the count), and can display them on their website.
Note that citations from Crossref may differ from those provided by other services because we only look for links between Crossref-registered works and don’t share the same method to find matches.
Obligations and fees for Cited-by
Participation in Cited-by is optional, but encouraged
There is no charge for Cited-by
You must include references when you register content in order to be eligible for Cited-by
You only retrieve Cited-by metadata for your own content.
Best practice for Cited-by
Because citations can happen at any time, Cited-by links must be kept up-to-date. Members should either check regularly for new citations or (if performing XML queries) set the alert attribute to true. This means the search will be saved in the system and you’ll get an alert when there is a new match.
Also in the metadata is the number of citations a work has received, under the tag "is-referenced-by-count".
However, to retrieve the full list of citations for your own works, you need to use Cited-by. While anyone can use an API query to see the number of citations a work has received, through Cited-by the member who deposited the work can retrieve a list of citing DOIs. Details of the citing works can be displayed on your website alongside the article.
In addition, Cited-by users can receive callback notifications or emails informing them when one of their works has been cited.
