Open Access Funding

Gold Open Access publication in this journal is supported by various funding routes to ensure that every author, irrespective of their circumstances, can enjoy the benefits of Gold OA. Prospective authors should submit with full confidence, knowing that no author will face a financial barrier to publication. The costs of publishing Gold OA may be covered in one of the following ways: 

• For corresponding authors at institutions that have an open access publishing agreement with Cambridge, in the majority of cases these cover the full costs of Gold OA. Eligibility is automatically established during the publication process. Prospective authors can use our eligibility checker to see if their institution has an active agreement.
• The Cambridge Open Equity Initiative (COEI) funds Gold OA for corresponding authors from over 100 low- and middle-income countries. Eligibility is automatically established during the publication process.
• Corresponding authors from low- and middle-income countries who are not covered by an institutional open access agreement or the Cambridge Open Equity Initiative may be eligible for support under the Research4Life scheme. 
• If authors have third-party funding available for the payment of article processing charges (APCs), for example as part of a research grant, they are asked to use this funding to pay an APC.
• Any corresponding author of a research article who is not covered by one of the above funding routes can request a discount or full waiver of their APC. Authors will be invited to make their request after editorial acceptance of their article, when completing their Author Information Form.

Please note that the decision whether to accept a paper for publication will rest solely with the Editor, and without reference to the funding situation of the authors. The Editor, editorial board members, and reviewers have no involvement with funding support for Gold OA and cannot grant APC discounts or waivers, which shall be assessed and provided by Cambridge. 

Please check the fees and pricing page for details of this journal’s charges, and our central APC page for further information such as APC refund policies.
