Open Access Types of Open Access

Gold open access allows access to articles at no cost to the reader directly from the journal’s web site. Journals may be fully open access or hybrid. Authors are generally required to pay an APC.

Green open access is repository-based open access. Authors may archive their own work on a website or in a repository. Archived versions may or may not be the final version.  

Diamond / platinum open access refers to academic texts published/distributed/preserved with no fees to either reader or author.
