Cambridge Core now offers a more secure way for authors to access and share access to their work.
In order for journal article authors to get access to their work on Cambridge Core, they will now receive an email with two codes: one for them to access their article and another for them to share with others who may also wish to access. Each group will then need to register on Cambridge Core (only once) and enter the code in 'My Content'. Once redeemed the article will become available.Please contact firstname.lastname@example.org with details of your article (article title, journal title, journal volume and issue) to receive your new access code for this article.
