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.
Our REST API makes all of the metadata we hold publicly available. It receives the majority of our API traffic, with around 1 billion hits per month. It’s one of the key ways that we fulfil our mission to make research objects easy to find, cite, link, assess, and reuse. From 1 December 2025, we will be revising the rate limits for the public and polite pools of the REST API to ensure that we can maintain a stable and reliable system, and that metadata is freely available to everyone.
Watch for two important emails on September 30th – one with a voting link and material, and one with your username and password.
Running Crossref well is a key part of our mission. It’s important that we be as neutral and fair as possible, and we are always striving for that balance. One of our stated principles is “One member, one vote”. And each year we encourage each of our members-standing at over 6000 today-to participate in the election of new board members.
It is hard to believe that November 2nd will be Crossref’s 17th annual meeting and our 16th annual Board of Directors election. How time flies, and oh, how we have grown!

I am hoping that we can rally the membership to participate in this important process!
Candidates will be elected at Crossref LIVE16 for three-year terms to fill five of the 16 Board seats whose terms expire this year. The slate of candidates was recommended by the Nominating Committee, which consisted of three Board members not up for re-election, and two Crossref members that are not on the Board.
This year, Jasper Simons, APA; Paul Peters, Hindawi; Jason Wilde, AIP; Chris Fell, Cambridge University Press; and Rebecca Lawrence, f1000 served on the Nominating Committee. The Committee met to discuss the process, criteria, and potential candidates, and put forward a slate which was required to be at least equal to the number of Board seats up for election. The slate may or may not consist of Board members up for re-election.
Crossref members are welcome to run as independent candidates, as long as they have ten member endorsements sent to lhart@crossref.org with the intent to run. We sent a notification of the process in advance (this year on August 26th), so any nominations could be included in the voting materials that will be sent via email on September 30th.
