Leiden University Open Access Policy

The Dutch government aims to ensure that in 2020 100% of peer reviewed articles funded with public money will be Open Access.

Open Access Policy

In order to realize a compliance that will allow Leiden University to meet the aims set by our government, the Executive Board updated the Leiden Open Access policy in 2017. The Board requests all Leiden researchers to make their peer reviewed articles Open Access available by means of LUCRIS and the Leiden Repository. This is an easy and straightforward way to facilitate open, transparent, and sustainable access to the research output produced by Leiden academics. There are no charges for the use of the Leiden Repository.

The policy emphasizes peer reviewed articles, because this category of publications is subject of goals set by the government. Needless to say, researchers are also encouraged to make other types of publications Open Access available through an upload into the Repository: book chapters, reports, congress proceedings, and other publications.

Making articles Open Access

  • How can I deposit my article?
    You can upload it into the Leiden Repository: you can do this by uploading a PDF file of the article upon registration of the publication in LUCRIS.
  • When can I deposit my article?
    Immediately after publication. If necessary, you can apply an embargo period in LUCRIS. After the date that you set has passed by, the article will become Open Access automatically.
  • Which version of the article can I use?
    The policies of publishers concerning uploads into institutional repositories vary per journal title:
    • The final published version or version of record/publisher’s pdf.
      If the article is Open Access available on the publisher’s website, you may use this version. You can recognize Open Access articles by a creative commons license (such as CC-BY or CC-BY-NC-ND); additionally, many publishers mark these publications with an ‘open access’ label.
    • Author’s version. 
      Check your publisher’s policy with the help of the JournalBrowser or via Sherpa/Romeo:
      • Postprint:
        your last version of the article, with all corrections after peer review applied, but without the lay-out and typesetting of the publisher.
      • Preprint:
        the version of the article that you submitted to the journal for peer review.

Making other publications Open Access

The Leiden Repository can be used in the same way to make other types of publications Open Access as well. The main difference with articles is that publishers’ policies are often not as explicitly stated. We recommend that you contact your publisher to make an agreement on deposits in institutional repositories before you publish.

If the publication is Open Access available on the publisher’s website, you may use this version. You can recognize Open Access publications by a creative commons license (such as CC-BY or CC-BY-NC-ND); additionally, many publishers mark these publications with an ‘open access’ label.

If the publication is not Open Access, you will have to check with your publisher which version you may use for the Repository, and whether an embargo period applies.
