Articles published under the Oxford Open model are made freely available online immediately upon publication, without subscription barriers to access. Authors who choose to participate in the Oxford Open initiative and pay to have their paper freely available online will be asked to sign an open access licence agreement. Our Oxford Open journals implement a variety of different Creative Commons licences. Some of our journals offer a single Creative Commons licence, while others may offer a choice of two or three. The licencing options available vary by discipline and are tailored to be most appropriate to the individual journal. Please check the 'Instructions to Authors' page of any journal to find out the exact policy for that title. The three open access licences which Oxford Open employs are CC-BY, CC-BY-NC, and CC-BY-NC-ND. You can find a summary of each licence below.
