Open access options

Under this journal’s Green Open Access policy, authors can make pre-published versions of their articles available in institutional or other repositories, or on their personal or departmental websites, under certain conditions. This allows authors to comply with the open access mandates of many funders and institutions. Please note however that this journal's Green Open Access policy does not meet the open access requirements of Plan S.  

For more information, please see Cambridge University Press’s Green Open Access policy page, where you can download a spreadsheet with full details about which versions of articles authors can post online, and where and when authors can post them. If you have open access questions which are not answered by our policy pages and resources, please contact

This journal follows Cambridge’s Green Open Access policy for scientific, technical and medical journals, which means an embargo of six months applies before authors can make accepted manuscripts available in non-commercial repositories. The embargo period starts from the date the article’s Version of Record is published online by Cambridge. 

Social Sharing

This journal participates in Cambridge Core Share, an initiative that allows a read-only version of a final published PDF (the Version of Record) to be shared and easily accessed by anyone. Core Share links, and Core Share PDFs containing the links, can be freely shared on social media sites and scholarly collaboration networks to enhance both the impact and discoverability of research. 

Preprint policy

A preprint is an early version of an article prior to the version accepted for publication in a journal. This journal allows preprints to be posted anywhere at any time, including before submission to the journal. For more information, see the Cambridge University Press preprint policy.
