This journal is a wholly open access journal, which means all articles are published as Gold Open Access under a Creative Commons licence. This enables anyone to access and redistribute the content and, depending upon the licence, re-use the content in new or derivative works with attribution. The terms of re-use for Gold Open Access content are stated in the copyright line of the article.
Authors may choose any of the six Creative Commons licences when publishing in this journal.
Gold Open Access is supported by an article processing charge (APC) typically paid by the author’s funding body or institution; please check the fees and pricing page for details of this journal's charges. Cambridge University Press has also made a number of agreements to support open access, and authors at participating institutions may be eligible for APC waivers and discounts.
Under this journal’s Green Open Access policy, authors can also 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.
If you have open access questions which are not answered by our policy pages and resources, please contact openresearch@cambridge.org.
Preprints
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.
Waivers for society members
IGS members who are acting as the corresponding author on a paper are entitled to a 10% discount on their article processing charge. Members wanting to take up this option will be able to do so during the payment process.
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.
