Research Integrity Roundtable 2024

For the third year in a row, Crossref hosted a roundtable on research integrity prior to the Frankfurt book fair. This year the event looked at Crossmark, our tool to display retractions and other post-publication updates to readers. Since the start of 2024, we have been carrying out a consultation on Crossmark, gathering feedback and input from a range of members. The roundtable discussion was a chance to check and refine some of the conclusions we’ve come to, and gather more suggestions on the way forward.

How good is your matching?

In our previous blog post in this series, we explained why no metadata matching strategy can return perfect results. Thankfully, however, this does not mean that it’s impossible to know anything about the quality of matching. Indeed, we can (and should!) measure how close (or far) we are from achieving perfection with our matching. Read on to learn how this can be done! How about we start with a quiz? Imagine a database of scholarly metadata that needs to be enriched with identifiers, such as ORCIDs or ROR IDs.

Update on the Resourcing Crossref for Future Sustainability research

We’re in year two of the Resourcing Crossref for Future Sustainability (RCFS) research.

Crossref is in a good financial position with our current fees, which haven’t increased in 20 years. This project is seeking to future-proof our fees by: Making fees more equitable Simplifying our complex fee schedule Rebalancing revenue sources In order to review all aspects of our fees, we’ve planned five projects to look into specific aspects of our current fees that may need to change to achieve the goals above.

Meet the candidates and vote in our 2024 Board elections

On behalf of the Nominating Committee, I’m pleased to share the slate of candidates for the 2024 board election. Each year we do an open call for board interest. This year, the Nominating Committee received 53 submissions from members worldwide to fill four open board seats. We maintain a balanced board of 8 large member seats and 8 small member seats. Size is determined based on the organization’s membership tier (small members fall in the $0-$1,650 tiers and large members in the $3,900 - $50,000 tiers).

Crossref Surpasses 30 Million DOI Mark

02 January 2008

LYNNFIELD MA, January 2, 2008 – Crossref, the well known linking service, announced today that it had recently registered its 30 millionth DOI. While the majority of Crossref’s Digital Object Identifiers® (DOIs)® are assigned to online journal articles, there are now over 2.5 million DOI names assigned to other types of publications, including conference proceedings, dissertations, books, datasets, and technical reports. Crossref’s dues-paying membership exceeds 500, with over 2,400 publishers and societies participating in Crossref linking.

The 30 millionth DOI, doi:10.1103/PhysRevE.76.055201 was registered by The American Physical Society for their journal Physical Review E.

Crossref adds an average of 550,000 new items every month to its DOI registry and linking service. Of the over 6.5 million DOIs created and assigned during the past year, a large number are associated with archival, or back-file, journal articles, as several large publishers have recently undertaken extensive retro-digitization projects. These include the Royal Society, Elsevier, Springer, Sage, Kluwer, Wiley, Blackwell, and the American Association for the Advancement of Science. In 2007 alone, the scholarly journal archive JSTOR added a total of 325,251 DOIs to Crossref.

Other noteworthy deposit events during the past year:

-The Office of Scientific and Technical Information (OSTI) of the U.S. Department of Energy deposited more than 86,000 DOE technical reports with Crossref, the earliest report dating from 1933.

-SciELO – The Scientific Electronic Library Online based in Brazil – added over 26,000 DOIs.

-The Persee Program, established by the Ministry of State Education, Higher Education and Research in France, deposited over 30,000 DOIs, of which over 14,000 were for legacy content.
