Preprints growth rate ten times higher than journal articles

The Crossref graph of the research enterprise is growing at an impressive rate of 2.5 million records a month - scholarly communications of all stripes and sizes. Preprints are one of the fastest growing types of content. While preprints may not be new, the growth may well be: ~30% for the past 2 years (compared to article growth of 2-3% for the same period). We began supporting preprints in November 2016 at the behest of our members. When members register them, we ensure that: links to these publications persist over time; they are connected to the full history of the shared research results; and the citation record is clear and up-to-date.

Linking references is different from depositing references

From time to time we get questions from members asking what the difference is between reference linking and depositing references as part the content registration process. Here’s the distinction: Linking out to other articles from your reference lists is a key part of being a Crossref members - it’s an obligation in the membership agreement and it levels the playing field when all members link their references to one another.

Over the past few months we have been adding to the metadata and functionality of our REST API, Crossref’s public machine interface for the metadata of all 90 million+ registered content items. Much of the work focused on a review and upgrade of the API’s code and architecture in order to better support its rapidly growing usage. But we have also extended the types of metadata that the API can deliver.
