Other routes to open access

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 before the final article is published as Gold Open Access. 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.
