About CORE

What is CORE?

CORE is the world’s largest aggregator of open access research papers from repositories and journals. It is a not-for-profit service dedicated to the open access mission. We serve the global network of repositories and journals by increasing the discoverability and reuse of open access content. We provide solutions for content management, discovery and scalable machine access to research. Our services support a wide range of stakeholders, specifically researchers, the general public, academic institutions, developers, funders and companies from a diverse range of sectors including but not limited to innovators, AI technology companies, digital library solutions and pharma.


CORE’s mission is to aggregate all open access research worldwide and deliver unrestricted access for all.

In doing so, we:

  • enrich scholarly data using state-of-the-art text and data mining technologies to aid discoverability,
  • enable others to develop new tools and use cases on top of the CORE platform,
  • support the network of open access repositories and journals with innovative technical, solutions and,
  • facilitate a scalable, cost-effective route for the delivery of open scholarship.

How it works

CORE harvests research papers from such as institutional and subject repositories, and open access and hybrid journals.
