Which types of open access exist?

Gold open access: You publish in a fully open access journal that does not charge subscription fees for reading access. Gold open access journals usually charge a publication fee, also known as an Article Processing Charge (APC).

Hybrid open access: You publish in a ‘traditional’ subscription journal that offers open access publication for individual articles on payment of an Article Processing Charge (APC).

Green open access: You publish in a closed access journal and then self-archive a version of your publication in a trusted open access repository, such as the University's research database. Publications can be archived upon publication or after, depending on the journal’s policy. It is often permitted to self-archive the author’s final version (post-print) after an embargo period.

Diamond open access: You publish in a fully open access journal or platform that does not charge any publication fees (APCs). The costs of publishing and hosting are borne by one or more organizations, associations or networks.
