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. This report provides an update on progress to date, specifically on research we’ve conducted to better understand the impact of our fees and possible changes. 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 Public Data File

You have an alternative to the REST API if your goal is to obtain the entire body of Crossref’s records. With the public data file you have access to every DOI ever registered with Crossref.

2024 Public data file

Tips for working with Crossref public data files and Plus snapshots

Important considerations:

  • The records are in JSON.
  • Metadata is supplied by our members and, as such, not all records have the same completeness or quality of metadata.
  • Every year our metadata corpus grows. The first data file was 65GB and held 112 million records; this year the file weighs in at 212 GB and contains metadata for 156 million records, or all Crossref records registered up to and including April 2024.
  • Decompressing the .tar.gz files will take you several hours.

Additional convenient tools:

Given the size and the amount of files that the public data files comprises, we started experimenting with some additional tools to improve access to the data and repack the data into additional formats:

These tools are experimental, so please remember that we they are released without warranties and support, but are happy to hear about your experience using them. You can read more about them in this blog post
