Cléo (Centre pour l'édition électronique ouverte) is a pivotal French service and research unit (USR 2004) dedicated to advancing open access digital publishing. It is the driving force behind OpenEdition, a comprehensive infrastructure offering four distinct platforms for scholarly communication in the humanities and social sciences: OpenEdition Journals (academic journals), OpenEdition Books (scholarly books), Hypothèses (research blogs), and Calenda (academic event announcements). Cléo operates under the joint supervision of major French research institutions: Centre National de la Recherche Scientifique (CNRS), Aix-Marseille Université (AMU), École des Hautes Études en Sciences Sociales (EHESS), and Avignon Université. Its core mission is to promote the widespread dissemination of research, foster digital scholarship, and ensure the long-term availability of academic content through innovative open electronic publishing solutions, primarily serving the academic community and the public.
Serves as the primary operational, research, and development hub for the OpenEdition portal and its associated platforms. Key functions include technical infrastructure management, software development, editorial support and training, user services, international partnerships, and administrative operations.
Located within a dynamic technopark, providing access to a rich ecosystem of research and technology. The OpenEdition Center is a modern facility designed to support digital scholarship and collaborative projects.
Characterized by a collaborative, innovative, and mission-driven environment. The culture emphasizes open science principles, academic rigor, interdisciplinary teamwork, and a strong commitment to serving the global research community. Staff often have strong academic backgrounds and a passion for digital humanities.
The Marseille headquarters is crucial to Cléo's national and international influence, acting as the nerve center for OpenEdition, one of Europe's leading platforms for open access in the humanities and social sciences. Its location facilitates engagement with a broad network of academic and research institutions.
Cléo achieves global presence primarily through its OpenEdition digital portal, which is accessed by users worldwide. While its physical offices are in France, OpenEdition's platforms host and disseminate scholarly content from international authors and institutions, supporting multiple languages (notably French, English, Spanish, Portuguese, and Italian). Cléo actively engages in international collaborations, partnerships with libraries, research consortia, and participates in global open science initiatives to promote and sustain open access for humanities and social sciences research across geographical boundaries.
