Overlay Journal Platform

What it is

A complete editing and publishing platform

Episciences is an overlay journal platform to host and disseminate diamond open access publications from all disciplines. The journals adhere to the FAIR principles (Findable, Accessible, Interoperable, Reusable).

Supported by the Centre pour la Communication Scientifique Directe, a support and research unit created by the CNRS, joining Inria and INRAE, Episciences offers technical and editorial support to journal teams from all over the world.

Preprints and articles published by Episciences overlay journals are hosted by open repositories such as arXiv, HAL and Zenodo.

Episciences is available through the OpenAIRE Service catalogue and the EOSC. The platform is connected to many OpenAIRE services, such as Zenodo, OpenAIRE Research Graph, ScholeXplorer, OpenCitations and UsageCounts.

Who is it for?

Episciences is for researchers:

  • as authors and readers;
  • as editors, reviewers and copy editors.

Journals have a non-exclusive right to publish the contents; by using Creative Commons licences, authors retain their rights.

Episciences allows researchers to save time, money, and effort, so they can focus only on their research.

Episciences is also open to anyone interested in reading sciences thanks to the diamond open access model that provides all content open access.

How can we use it?


episciences schema

1 An author deposits a preprint in an open repository such as HAL, arXiv or Zenodo.
2 Then he submits it to an overlay journal.
3 The editorial board of the overlay journal examines the submission and entrusts its expertise to reviewers.
4 The expertise received - which can be rejected, accepted subject to modifications, or accepted as is—is transmitted to the author.
5 The revised article gives rise to a new version that is deposited in the open repository: This new version will be reviewed once more by the reviewers before being accepted or leaving for a new round of evaluation.
6 Once the article has been definitively validated by the journal’s editorial board, then copy-edited and deposited in the open repository, it is published on the journal’s website and receives a DOI.
