To date, most Gold Open Access journals have adapted the publishing model used by traditional journals. The main variation has been to move costs from individual or library subscriptions to author(s). If an article is accepted for publication, author(s) pay an Article Processing Charge (APC) to the journal publisher to have their article published.
