The Centre pour la Communication Scientifique Directe (CCSD) and the Confederation of Open Access Repositories (COAR) announced on 5 October 2022 the launch of a directory of preprint servers: DOAPR, Directory of Open Access Preprint Repositories, designed to guide researchers in their search for a preprint repository adapted to their needs and satisfying open science criteria, while providing them with an overview of the preprint ecosystem.

Preprints are becoming an increasingly important part of the research communications landscape. Posting preprints allows researchers to share their research freely and rapidly with their colleagues and the broader community.

However, the community has no single tool to view the current preprint landscape. Existing registries are either exhaustive and cover all types of repositories or focus on preprints in a single discipline. This directory brings together all repositories that collect preprints into a single database, enabling users to choose the most suitable platform for their needs, and to have an overview of the preprint ecosystem.

The directory is built on the outcomes of a project undertaken by the French Committee for Open Science (Preprints Platforms Project) and supported by the French Ministry of Higher Education and Research (MESR), which developed an extensive and detailed catalogue of preprint repositories. The current list of preprints documents over 90 preprint repositories along with details about their management, functionalities, and related services and their relation to open science criteria.

As part of the collaboration, COAR is hosting the preprint directory and CCSD is curating the metadata records ensuring the registry remains up-to-date.

The directory is available here: https://doapr.coar-repositories.org/
