Scholarly metadata, deposited by thousands of our members and made openly available can act as “trust signals” for the publications. It provides information that helps others in the community to verify and assess the integrity of the work. Despite having a central responsibility in ensuring the integrity of the work that they publish, editorial teams tend not be fully aware of the value of metadata for integrity of the scholarly record. How can we change that?
Crossref was created back in 2000 by 12 forward-thinking scholarly publishers from North America and Europe, and by 2002, these members had registered 4 million DOI records. At the time of writing, we have over 23,600 members in 164 different countries. Half of our members are based in Asia, and 35% are universities or scholar-led. These members have registered over 176 million open metadata records with DOIs (as of today). What a difference 25 years makes!
In our 25th anniversary year, I thought it would be time to take a look at how we got here. And so—hold tight—we’re going to go on an adventure through space and time1, stopping every 5 years through Crossref history to check in on our members. And we’re going to see some really interesting changes over the years.
The Frankfurt Book Fair is the largest book fair in the world, and therefore a key event on our calendar. Held annually in Frankfurt, Germany, the 77th Frankfurt Book Fair (October 15–19, 2025) saw 118,000 trade visitors and 120,000 private visitors from 131 countries. The Crossref booth was located, as usual, in Hall 4.0 where all the stands with information about academic publishing can be found. Four Crossref colleagues attended the Book Fair this year, and in this blog post, you can read more about their meetings, experiences, and plans.
TL;DR. Metadata Manager will be retired at the end of 2025. Over the past four years, we have been developing a new helper tool to replace it, and that tool has now reached a stage of maturity that means we will be able to switch off Metadata Manager by the end of the year.
The DOI error report is sent immediately when a user informs us that they’ve seen a DOI somewhere which doesn’t resolve to a website.
The DOI error report is used for making sure your DOI links go where they’re supposed to. When a user clicks on a DOI that has not been registered, they are sent to a form that collects the DOI, the user’s email address, and any comments the user wants to share. We compile the DOI error report daily using those reports and comments, and send it via email to the technical contact at the member responsible for the DOI prefix as a .csv attachment.
If you would like the DOI error report to be sent to a different person, please contact us.
The DOI error report .csv file contains (where provided by the user):
DOI - the DOI being reported
URL - the referring URL
REPORTED-DATE - date the DOI was initially reported
USER-EMAIL - email of the user reporting the error
COMMENTS
We find that approximately 2/3 of reported errors are ‘real’ problems. Common reasons why you might get this report include:
you’ve published/distributed a DOI but haven’t registered it
the DOI you published doesn’t match the registered DOI
a link was formatted incorrectly (a . at the end of a DOI, for example)
a user has made a mistake (confusing 1 for l or 0 for O, or cut-and-paste errors)
What should I do with my DOI error report?
Review the .csv file attached to your emailed report, and make sure that no legitimate DOIs are listed. Any legitimate DOIs found in this report should be registered immediately. When a DOI reported via the form is registered, we’ll send out an alert to the reporting user (if they’ve shared their email address with us).
I keep getting DOI error reports for DOIs that I have not published, what do I do about this?
It’s possible that someone is trying to link to your content with the wrong DOI. If you do a web search for the reported DOI you may find the source of your problem - we often find incorrect linking from user-provided content like Wikipedia, or from DOIs inadvertently distributed by members to PubMed. If it’s still a mystery, please contact us.
