Open Access

What is Open Access

Open Access is the free, immediate, online access to the results of scholarly research, and the right to use and re-use those results as you need.

An Open Access publication is immediately available online - without costs - to read, download, copy, print, disseminate or search.

An author can choose between two Open Access roads:

  1. publish in a subscription journal, then self-archive an Open Access copy of the article in Cadmus, the EUI Research Repository or in a subject repository (Green OA)
  2. publish in an Open Access journal or a ‘hybrid’ journal with an OA option (Gold OA)

@ the EUI

The EUI supports the principle of Open Access and encourages scholars to facilitate the widespread dissemination of their research by making their publications available in Cadmus, the EUI's Research Repository.

Many EUI PhD theses are available online, either in immediate open access or after a 4-year embargo. Browse EUI Open Access theses. Read on how to make the EUI thesis available online or this library blog post on EUI theses.

The EUI has signed two milestone declarations of the open access movement:

The EUI offers Dissemination Support for EUI Research Projects funded by Horizon 2020 and ERC. Project Directors are encouraged to complete a Checklist and form.

Open Data guidelines are in the Research Data Guide

Cadmus is searchable in and harvested by several European and international networks and portals. Some are listed below.

European Research Council (ERC)


OpenAIRE is a network of Open Access repositories, archives and journals that support Open Access policies. OpenAIRE started out as a policy support mechanism for the EC (FP7 pilot and H2020 OA policies), with the aim to be the European scholarly communication hub providing its services to many European funders. Its predecessor, Driver, was in 2014 merged with the OpenAIRE infrastructure.

Cadmus is certified OpenAIRE compliant since 2013. More information on Cadmus in OpenAIRE.


The EU Framework Programme for Research and Innovation, Horizon2020, is the biggest EU Research and Innovation programme ever with nearly €80 billion of funding available over 7 years (2014 to 2020)

Search for projects in Cordis containing EU-funded projects since 1990.


The European E-theses portal Dart contains nearly 700,000 Open Access full-text theses. It is a partnership of research libraries and library consortia who are working together to improve global access to European research theses. Dart harvests the EUI open access theses in Cadmus, and EUI theses are therefore found also in the Dart E-theses Portal.


Italy's national portal for Electronic Scientific Litterature of Institutional Repositories, Pleiadi, harvests the scientific production of Italian universities and research institutes and has nearly 3 million records. Cadmus content is searchable from Pleiadi.

Registry of Open Access Repository Mandates and Policies (ROARMAP)

ROARMAP is an international registry of open access mandates and policies (adopted by universities, research institutions and research funders) that require or request their researchers to provide open access to their peer-reviewed research article output by depositing it in an open access repository. The Open Access Check Tool tells you if a ROARMAP registered OA policy corresponds to H2020 OA guidelines. 


WorldWideScience.org is a global science gateway—accelerating scientific discovery and progress through a multilateral partnership to enable federated searching of national and international scientific databases and portals. Cadmus content is searchable from Worldwide science via Pleiadi, and via OpenAIRE.
