Scholarly Communication: Karger Open Access

Karger Open Access Agreement


NUS Libraries has entered into a 3-year deal with Karger. For all submissions to Karger Open Access and Hybrid journals (except the Kompass journal series, which are by invitation only) made between Jan. 1, 2021 and Dec 31, 2023, NUS corresponding authors can publish open access without incurring Article Processing Charges using their institutional email and specifying their institutional affiliation during the manuscript submission process. For instructions on the submission process, please check out the guide below.

If you have any questions regarding this agreement, please contact the Scholarly Communication team.

How does the agreement affect me?

As an NUS-affiliated author* of a Karger Open Access or Hybrid journal article between Jan. 1, 2021 and Dec. 31, 2023, you are affected in two ways:

NUS corresponding authors: You are able to publish your article submitted Open Access without incurring Article Processing Charges by using your institutional email and specifying your institutional affiliation to be ‘National University of Singapore’. A copy of your open access article will also be deposited into Scholarbank@NUS, NUS' institutional repository the next quarter from the published date. If you do not wish to publish Open Access, you may select the ‘Opt Out despite being eligible’ option and publish your work in Karger as subscription-only, paywalled content.

NUS co-authors: If you are a co-author of an article, but not the corresponding author, a copy of your article will be deposited into Scholarbank@NUS, NUS' institutional repository the next quarter from the published date.


*To ensure your eligibility, please use your NUS email (emails ending with;;; during article submission.

Why Open Access and how to publish Open Access?

There are several reasons why it is advantageous to publish open access;

  • Making your publications 'Open Access' improves the visibility of your work as it can be read by everyone
  • Allows your research findings to be disseminated quickly via multiple channels
  • Allows you to retain your author's rights to your research publications
  • Several funding bodies (e.g. MOE Tier 2 and 3, NRF Competitive Research Programme and ASTAR) require grant holders to make their publications open access.


There are two models to make your publications open access.

  • "Gold" or immediate OA - This ensures that your article becomes open access immediately on publication. Very often, an article processing charge (APC) is paid to the publisher. Gold OA is available to fully open access journals, as well as for hybrid journals which are traditional journals offering both open access and non-open access publishing models.
  • "Green" OA - This involves publishing in a subscription journal and then making a version of your article (i.e. preprint, postprint, and/or published PDF) available through a repository such as the institutional repository, ScholarBank@NUS. You may be required to deposit after an embargo period of up to a year. To find out more information, please check Sherpa Romeo for journal OA and copyright options.
