Evolving the preprint evaluation world with Sciety
This post is based on an interview with Sciety team at eLife.
A lot of people have been using our public, open APIs to collect data that might be related to COVID-19. This is great and we encourage it. We also want to make it easier. To that end we have made a free data file of the public elements from Crossref’s 112.5 million metadata records.
The file (65GB, in JSON format) is available via Academic Torrents here: https://doi.org/10.13003/83B2GP
It is important to note that Crossref metadata is always openly available. The difference here is that we’ve done the time-saving work of putting all of the records registered through March 2020 into one file for download.
The sheer number of records means that, though anyone can use these records anytime, downloading them all via our APIs can be quite time-consuming. We hope this saves the research community valuable time during this crisis.
All records are included. In other words, the data file has every DOI ever registered with Crossref through March 31st, 2020. This means it’s a large file, 65GB.
The records are in JSON.
New and updated records can be added incrementally using our REST API, which includes a number of date filter options, e.g. index-date.
No registration is required to use our REST API but we do strongly encourage being a ‘polite’ (i.e. identified) user. It makes troubleshooting much easier and reduces the chance of negatively impacting other users.
Questions, comments and feedback are welcome at support@crossref.org.
We thank AcademicTorrents.com for helping us make this data available. And we are grateful for the incredible efforts of everyone working to support research everywhere–stay safe and well.
