CORE updates and a reminder of some highlights


The CORE team had a busy end to 2020! In the October to December quarter, CORE broke records, partnered with and continued improving our REF2021 compliance monitoring service.  Our team concentrated on multiple areas, including collaboration with the open access community and new feature development.

Community collaborations

Abstracts logo
  • CORE is delighted to become a stakeholder of the Initiative for Open Abstracts (I4OA). I4OA is contributing a very positive step to our jointly held goals to further open research. As an aggregator of research content, we understand the importance of the article metadata, including the abstract, being centrally and openly available. We look forward to further collaborating with I4OA. More details can be found in CORE’s blog post. 
  • During the celebrations of Open Access Week 2020, Nancy Pontika presented a webinar on “Closing the scientific literature access gap with CORE – how to gain free access to millions of open access scientific papers” in conjunction with Kerala Library Association. The webinar was live-streamed and recorded. The slides are also available online.
