Scholarly publishing: Open access

What is Open Access

Open access (OA) literature is digital, online, free of charge, and free of most copyright and licensing restrictions, thus ensuring that all readers have access to scholarship. This means that your research findings and publications will be accessible to the scholarly community and the larger public as they can freely read and download your research publications.

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.
