An ambitious free index of more than 200 million scientific documents has been launched

. “We now have much better coverage of open access than MAG ever did,” Priem says. “Not only can we tell you where the free-to-read copies of any particular article live, but we can also tell you the licence and the version of that article.”

Priem says that OpenAlex updates every fortnight by bringing in more data from its sources. The tool goes a step further towards openness than MAG did, because OpenAlex’s underlying code is freely available under a CC0 copyright licence for anyone to build on, says Priem. That means that if OpenAlex were to be discontinued, any researcher can pick up where Priem left off instead of having to rebuild the whole database from scratch.

It’s “written in such a way that’s very easy for somebody to pick up and use”, says Adie. He adds that it took him only about 20 minutes to get started on OpenAlex, compared with three to four days with MAG. “The downside is that Microsoft had a lot of technical capability that they could apply to Microsoft Academic. So we’ll have to see how OurResearch does without that,” Adie says.

Roar Bakken Stovner, who studies researchers’ citations patterns at Oslo Metropolitan University, says that it took him around two hours to start working with OpenAlex, compared with around a week with MAG. “For somebody who is more computer savvy, MAG might be easier,” he says. “For researchers who want to try small projects on their own, OpenAlex will be way easier to start with.”

Frode Opdahl, chief executive of Keenious, a start-up firm based in Tromsø, Norway, which scans millions of papers to suggest relevant references, says he’s pleased with the documentation published about OpenAlex. “It makes it a lot easier to work with and implement into our product,” he says.
