OpenEdition: Platforms, Search and Freemium

OpenEdition is a digital resources portal for the humanities and social sciences. It is not a researcher registry and it does not issue an identifier: it is a set of four publishing and discovery platforms (books, journals, research blogs and event announcements) run by the OpenEdition Center, a French public research-support unit. This guide explains what each platform is for, how to search them, what an institutional subscription adds, where to start if you want to publish, and how OpenEdition records reach library and discovery systems. Facts below come from OpenEdition’s own pages, checked on 2026-10-29.

What OpenEdition is

OpenEdition describes itself as a digital resources portal for the humanities and social sciences. Its homepage says it “brings together four platforms dedicated to electronic resources in the humanities and social sciences.” The site is available in English and French.

The operator is the OpenEdition Center, a CNRS research support unit (UAR 2504, which took over from USR 2004 in 2022). The partners listed on the homepage are CNRS, Aix-Marseille Université, EHESS and Avignon Université. According to its about page, the project began in 1999 as Revues.org at Avignon, became the Centre for Open Electronic Publishing (Cleo) in 2007, was recognised as a national research infrastructure in 2016, and was renamed the OpenEdition Center in 2018.

The four platforms: which one do you need?

The platform names below are the official labels on the OpenEdition homepage and about page.

Platform	What the official site says it holds	Use it when you want to
OpenEdition Books	Books	Find or publish a book
OpenEdition Journals	Journals	Read articles or look at a journal’s publisher page
Hypotheses	Research blogs	Follow or open an academic research blog
Calenda	Calls for papers, conferences, study days	Find or announce a call for papers or an academic event

On the OpenEdition homepage on 2026-10-29, the counters showed roughly 16,655 books, 676 journals, 5,140 blogs and 62,812 events. These counters change as content is added, so treat them as a dated snapshot rather than a fixed figure. A journals page on the same site states that 95% of its 150,000 articles are available in full text; that figure is also the site’s own and was checked on 2026-10-29.

How to search OpenEdition

Use the “OpenEdition Search” link on the homepage to search across all four platforms at once. Each platform also has a “Go to catalogue” link that opens its own browsable listing, OpenEdition Books has subject filters, and RSS feeds are offered. A practical order for most researchers is to start with OpenEdition Search to see where a topic appears, then move to the catalogue of the platform that holds the type of document you need.

If you are comparing OpenEdition with general scholarly search tools, see metadata search engines for scholarly research. OpenEdition covers the humanities and social sciences.

Free access versus Freemium

OpenEdition operates a “Freemium” model. Its about page says Freemium launched in 2010 for libraries and their users. The homepage says that if you want your university to subscribe to additional services and give you access to downloadable formats (PDF, ePub), you should go to the Institutions section; the links are labelled “Freemium programme” and “OpenEdition Freemium sales offer”.

In practice this means two separate questions. Can I read the text online? That is a question about the platform and the specific title. Can I download a PDF or ePub? On OpenEdition’s own description, that is the extra service an institution subscribes to. Ask your library whether it takes part in the Freemium programme. For licence terms on a particular book or journal, read the “OpenEdition Books License”, “Licensing Policy” and “Creative Commons Licenses” pages linked in the site footer, because the terms are set per publication.

For the wider picture of how open-access books are funded and licensed, see open access book and monograph publishing explained. France’s university library consortium is covered in how Couperin negotiates national open-access deals.

Publishing: where to apply

OpenEdition has separate application routes for each platform. The homepage links to pages labelled “How to apply for OpenEdition Journals”, “How to apply for OpenEdition Books”, “Application request for a research blog”, and “Submitting a Calenda announcement”. There is also a training page labelled “Using Lodel for electronic publication”.

The OpenEdition terms of use (the “GTCU”) state that each platform has its own terms for contributors and users, and that acceptance is subject to the acceptance of your application by the Scientific Council. Read the apply page for the platform you are interested in before you contact anyone.

Metadata exports and how records reach discovery systems

OpenEdition is a research infrastructure, not an identifier registry, so there is no OpenEdition “ID” to link to your ORCID record. What the site does publish is a set of machine-readable access points, listed in the footer: an ISBN resolver, an OAI-PMH repository, MARC records and KBART files. In general terms, OAI-PMH is a protocol for harvesting metadata, MARC is the library catalogue record format, and KBART is a knowledge-base format that libraries use to load holdings into link resolvers. These are the routes by which OpenEdition titles can appear in library catalogues and discovery layers.

On the identifier side, our guide to IdRef, France’s national researcher identifier notes that IdRef aligns with French platforms including OpenEdition. For indexing of journals in international databases, see journal indexing in DOAJ, Scopus and Web of Science. Whether a particular OpenEdition title is in a given index has to be checked in that index.

Common problems

Cannot download a PDF or ePub. Downloadable formats are described as an institutional service. Check with your library whether it subscribes through the Freemium programme.
Expecting a registration number. OpenEdition publishes and indexes content; applying to a platform is an application to publish, reviewed by the Scientific Council, not an identifier registration.
Looking for the old name. Revues.org is the earlier name of what is now OpenEdition Journals.
Quoting old figures. Older pages and conference slides give smaller counts. Quote the homepage figure together with its date.
Terms question. The terms of use page gives a contact address for questions about the terms; use the contact details shown on that page.
