Routes to open access

Publishing open access is possible via the gold and the green routes:

  1. Gold route: publish open access via a journal, which often requires paying an Article Processing Charge (APC). APCs can sometimes be reimbursed because of Big Deals made between publishers and university libraries. According to Plan S, the open access journals have to fulfill several requirements that you can find here".
  2. Green route (self-archiving): publish a version of your article in an institutional repository (RePub for the EUR) after publishing it via a journal.
    • Each repository should be registered in the Directory of Open Access Repositories (OpenDOAR)
    • You can check which version of your article (submitted, accepted or published) you can archive in a repository in Sherpa Romeo

A preprint is the submitted, non-peer reviewed version of your article. An increasing number of researchers publish preprints in Preprint servers in order to get their results out there quicker. Read more below and in this preprint FAQ.

Why publish preprints?

Where to publish preprints?

Preferably a preprint server that provides a persistent identifier. For example:

Feedback and updating

There are different ways researchers can give/receive feedback on preprints: - In OSF preprints, you can use their tool to annotate preprints, see their help guide - Some servers offer comment functionalities (e.g., when logged in) - Use (academic) twitter

What you do with feedback is completely up to you. If you want, you can update your preprint to a new version. However, note that all versions are timestamped and retained. Often new versions get a new identifier (DOI) and old versions cannot be removed! If your work gets published by a publisher, many preprint servers also offer the possibility to refer to the identifier (DOI) of your published work, so that readers of the preprint get a notification that they are not reading the most up-to-date version.
