Fully open access journals

Fully open access journals make all published articles immediately free to read and reuse without any subscription charges or access fees. To support the cost of managing peer review and publication, applies an article publication charge (APC) for published articles (or an article publication fee for journals published on behalf of the AAS). For some of our journals, APCs are not charged if IOP Publishing or one of our publishing partners is sponsoring the costs of publication. A full list of APCs can be found on our APC pricing page.

IOP Publishing and our publishing partners publish the following fully open access journals:


Materials Science

Multidisciplinary Physical Science

Environmental Science

Astronomy and Astrophysics
