TL;DR About 11% of available references in records in our OAI-PMH & REST API don’t have DOIs when they should. We have deployed a fix, but it is running on billions of records, and so we don’t expect it to be complete until mid-April.

Conflict, instability and economic conditions are just some of the factors driving new migration into Europe—and European policy makers are in dispute about how to manage and cope with the implications.

Nowadays we’re all trying to eat healthier, get fitter, be more mindful and stay in the now. You think you’re doing a good job — perhaps you’ve started a yoga class or got a book on mindfulness. And then, wham!

Hello. Isaac here again to talk about what you can tell just by looking at the prefix of a DOI.

In December, Crossref’s Head of Metadata, Patricia Feeney and I headed to Mumbai for our first ever LIVE local event in India, held in collaboration with Editage. Crossref membership in India has escalated in recent years, with a fifth of its 500 members joining in 2017 alone.

This is a long overdue followup to 2016’s “URLs and DOIs: a complicated relationship”. Like that post, this accompanies my talk at PIDapalooza, the festival of open persistent identifiers). I don’t think I need to give a spoiler warning when I tell you that it’s still complicated.

Hi, Crossref blog-readers. I’m Shayn, from Crossref’s support team. I’ve been fielding member questions about how to effectively deposit metadata and register content (among other things) for the past three years.

UPDATE, 12 December 2022 Due to the scheduled sunsetting of Metadata Manager, this title transfer process has been deprecated. Please find detailed guidance for transferring titles on our documentation site here.

Running a smooth event is always the goal, but not always the case! No matter how well managed an event is, there is always a chance that things will not go according to plan. And so it was with LIVE18.

In my previous blog post, Matchmaker, matchmaker, make me a match, I compared four approaches for reference matching. The comparison was done using a dataset composed of automatically-generated reference strings.

As the end of the year approaches it’s useful to look back and reflect on what we’ve achieved over the last 12 months—a lot!
