Detective Matcher stopped abruptly behind the corner of a short building, praying that his loud heartbeat doesn’t give up his presence. This missing DOI case was unlike any other before, keeping him awake for many seconds already.

Update: Deadline extended to 23:59 (UTC) 13th March 2020. Distributed Usage Logging (DUL) allows publishers to capture traditional usage activity related to their content that happens on sites other than their own so they can provide reports of “total usage”, for example to subscribing institutions, regardless of where that usage happens.

Our paper, Crossref: the sustainable source of community-owned scholarly metadata, was recently published in Quantitative Science Studies (MIT Press). The paper describes the scholarly metadata collected and made available by Crossref, as well as its importance in the scholarly research ecosystem.

Where does the time go… In my blog post on January 14th about Crossref’s 20th anniversary I said, “The one constant in Crossref’s 20 years has been change”. It’s true that there has been constant change, but there has been another constant at Crossref –– me (and DOIs, to be fair). I started as Crossref’s first employee and Executive Director on February 1st, 2000, so I just marked my 20th anniversary with the organisation.

Over the past few years, I’ve been really interested in seeing the breadth of uses that the research community is finding for the Crossref REST API. When we ran Crossref LIVE Kyiv in March 2019, Serhii Nazarovets joined us to present his plans for the Open Ukrainian Citation Index, an initiative he explains below. But first an introduction to Serhii and his colleague Tetiana Borysova.

It seems like only yesterday… On January 19th, 2000 a new not-for-profit organisation was registered in New York State. It was called Publishers International Linking Association, Inc but was more commonly referred to as “CrossRef”. This means that Crossref will be 20 years old on January 19th, 2020 so I wanted to mark the occasion with a short post. We are planning more ways to mark our 20th anniversary later this year so keep a lookout.

It’s been a year since Metadata Manager was first launched in Beta.  We’ve received a lot of helpful feedback from many Crossref members who made the switch from Web Deposit Form to Metadata Manager for their journal article registrations. The most common use for Metadata Manager is to register new DOIs for newly published articles. For the most part, this is a one-time process.  You enter the metadata, register your DOI, and success!

Isaac Farley, technical support manager, and Jon Stark, software developer, provide a glimpse into the history and current state of our popular monthly resolution reports. They invite you, our members, to help us understand how you use these reports. This will help us determine the best next steps for further improvement of these reports, and particularly what we do and don’t filter out of them. Isaac joined Crossref in April 2018.

English version –– Información en español In this post, Arley Soto shares some experiences about his work as a Crossref ambassador in Latin America. When I joined as a volunteer Crossref ambassador in 2018, I never imagined that in less than two years, I would have the opportunity to travel to three

I’m happy to announce that Lucy Ofiesh has joined Crossref as our new Director of Finance and Operations. Lucy has experience supporting the sustainability and governance of not-for-profit organisations having held roles such as Executive Vice President of the Brooklyn Children’s Museum and for the last few years as Chief Operating Officer at Center for Open Science, a Crossref member.

The first version of our metadata input schema (a DTD, to be specific) was created in 1999 to capture basic bibliographic information and facilitate matching DOIs to citations. Over the past 20 years the bibliographic metadata we collect has deepened, and we’ve expanded our schema to include funding information, license, updates, relations, and other metadata.
