Open access publication fees, also known as Article Processing Charges (APCs), are fees charged by publishers to authors who wish to publish their articles open access. These fees cover the costs of making an article freely available online, such as peer review, production, and hosting. APCs are typically charged to the corresponding or first author.
To ensure open access:
APCs are used by open access journals in lieu of subscription fees that libraries and readers have traditionally paid.
To provide wider access to research:
Open access articles are freely available to anyone with an internet connection.
To offset publication costs:
APCs help cover the costs of peer review, production, and online hosting and archiving.
