Celebrating 20 years of Cadmus, the EUI Research Repository

A- A A+

Today it is 20 years since the European University Institute (EUI), in 2003, established its research repository, Cadmus, to collect and share all the EUI’s research outputs. Our gift to Cadmus is the new temporary logo, also on Cadmus Home Page!

Why the name Cadmus?

Cadmus is known as the founder and the first king of Thebes, a powerful town in the ancient times, close to Athens. He is also known as the person who brought the alphabet from the Phoenicians to the Greeks. He was the brother of Phoenix, Cilix and Europa. What name could be a better fit for the tool that serves to share all the research and knowledge of the EUI?

Cadmus growth in number of publications

This year Cadmus turns 20 years’ old! The first milestone of 10,000 records was reached in April 2011, the second of 20,000 in February 2017, and the third in October 2020 when Cadmus reached 25,000 records. In 20 years, we have collected nearly 30,000 items of EUI research output, whether they be books, book chapters, working papers, theses, articles, datasets or technical reports.


Making EUI Research Output visible

The EUI Open Access Policy states that “The EUI supports the principle of Open Access and invites the academic community to facilitate the widespread dissemination of their published research by reporting and self-archiving their publications with Cadmus, the EUI Research Repository (green OA) and publishing Open Access articles in journals (gold OA)”.

Cadmus fulfils four different, yet related, roles and commitments:

  1. it is the Registry of all EUI research output, and it serves as the source for annual EUI activity reports
  2. it offers Open Access availability, retrievability and visibility to EUI research results. Cadmus has a very high proportion of Open Access; 70% of EUI 2022 outputs are available in Open Access. EUI authors self-archive their publications previously published by external publishers, e.g. journal articles, in Cadmus as green open access
  3. it is a Publishing platform:  the EUI academic community writes more than 1000 publications every year and nearly 40% of these are published in Cadmus (under EUI imprint)
  4. Since 2020, Cadmus hosts special collections like the COVID-19 Pandemic, the State of the Union, the Conference for the Future of Europe, and Ukraine. This development has opened a small road of broadening the traditional academic material to blogposts, recorded audio/video material and preprints.

Cadmus is fully integrated with EUI Profile pages as well as ORCID, and is indexed by Google Scholar, OpenAire, Worldcat and many other international portals. In 2022 the Library performed a system upgrade and migration of Cadmus. It is since then hosted on a cloud system to guarantee a more stable and secure environment.

Cadmus growth of Open Access

Between 2009 and today the proportion of Open Access publications in Cadmus has more than doubled: from 22 % to 45 % of all its content.
