Creative Commons for Researchers: a Practical Guide

The licences

The six licence types

The basic condition in all the licences is that users must provide attribution (credit) to the creator of the work, and include other key information such as the source of the original work, the licence under which it has been distributed, and if any changes have been made by the user. 

See also guidance on licence type compatibility and Creative Commons public domain tools.

Applying the licences

Marking your work

It's good practice for a creator to mark their work with their chosen licence, and you can generate a suitable line of text or code for this purpose using the Creative Commons Licence Chooser. The Creative Commons wiki offers some best practice guidance for marking your work, including considerations for different formats and marking third party content (material created by others).

For scholarly articles authored by York staff, the University Research Publications & Open Access Policy recommends that submitted articles should include the following text in the funding acknowledgement section of your manuscript and in any cover letter/note accompanying the submission:

For the purpose of open access, the author has applied a Creative Commons Attribution (CC BY) licence to any Author Accepted Manuscript version arising from this submission.

For some research funders, such as UKRI, Wellcome and NIHR, including this or a similar statement is a formal obligation, and is sometimes referred to as a 'rights retention statement' (see our Open Access Publishing Practical Guide for specific information on funder policies).

Creative Commons licensing options are supported by a wide range of research-hosting platforms. This includes publisher sites, platforms such as GitHub and OSF, and institutional repositories such as Pure and White Rose Research Online, which allow authors to select a licence at the point of deposit. Our research theses repository White Rose eTheses Online also provides licensing options for postgraduate researchers. 

How they work

Validity and durability

The current set of licences (version 4.0) are internationally valid and can be applied to a wide range of works including text, databases, images and basically any other formats except for software (see right). Older versions of the licences could be localised (ported) to different jurisdictions, but Creative Commons now advise against using these versions as they are not kept up to date and may not be internationally valid (see Frequently Asked Questions: Should I choose an international license or a ported license?). 

Creative Commons licences are technically irrevocable. If a creator has control over the distribution of a licensed work then they can cease sharing it under a particular licence (or make the work available under different terms, as Creative Commons licences are non-exclusive), but anyone who still has access to a copy of the work is entitled to continue using it under the original licence that was applied.

Creative Commons Licences remain valid for as long as the underlying copyright lasts. Generally speaking this will be until 70 years after the death of the author - see Copyright law explained for more information on copyright durations. Once copyright has expired, the work will enter the public domain and is free from any usage restrictions. 

Licence design

Three Layers of Licence image, showing the legal code, human readable and machine readable layers of a CC licenceThe licences are basic but innovative in design, comprising three layers: the legal code, the 'human-readable' Commons Deed and the machine readable code that can be embedded in a variety of file types (see About the Licences on the Creative Commons site for further information).

The licences do not automatically detect misuse of a work, but they put the creator in a strong (and legally enforceable) position to approach anyone they discover misusing the work, and ask them to stop. Creative Commons provide further advice on steps that creators can take if they believe a user has violated licence terms in their treatment of the work.
