Is permission required FAQs: using open access content
There are different types of Creative Commons open access licences. These open access licences remove some of the restrictions applied by copyright law, so that content published under them may be used without permission in certain conditions.
Each licence grants different reuse rights:
Some allowing reuse for commercial purposes
Some only allowing reuse for non-commercial purposes, as indicated by 'NC' in the licence title
Some only allowing the whole work to be used in its entirety, as indicated by 'ND' in the licence title
Some only allowing the work to be used if it is reused under the same licence, as indicated by 'SA' in the licence title.
This table sets out which Creative Commons licences IOP Publishing can use content published under without permission.
Therefore, if the content/figure you wish to reuse in your article/ebook has been published under a Creative Commons licence, check this table below to see whether you need to obtain permission. Full licence terms should still be checked and must be adhered to.
|Licence||Summary||Can authors use in a journal/ebook without permission?|
|CC BY||This licence lets others distribute, remix, tweak and build upon your work, even commercially, as long as they credit you for the original creation||Yes; allows commercial use|
|CC BY-SA||This licence lets others remix, tweak and build upon your work even for commercial purposes, as long as they credit you and license their new creations under the identical terms||Yes; allows commercial use but must make content available under same licence|
|CC BY-NC||This licence lets others remix, tweak, and build upon your work non-commercially, and although their new works must also acknowledge you and be non-commercial, they don’t have to license their derivative works on the same terms||No; only allows use for non-commercial purposes|
|CC BY-ND||This licence allows for redistribution, commercial and non-commercial, as long as it is passed along unchanged and in whole, with credit to you||Yes, but only if it is the entire work which is reproduced|
|CC BY-NC-SA||This licence lets others remix, tweak and build upon your work non-commercially, as long as they credit you and license their new creations under the identical terms||No; only allows use for non-commercial purposes|
|CC BY-NC-ND||This licence is the most restrictive of the six main Creative Commons licences, only allowing others to download your works and share them with others as long as they credit you, but they can’t change them in any way or use them commercially.||No; only allows use for non-commercial purposes|
A full citation, including the licence under which the content was originally published (and a link to that licence) must be included whether or not permission is required.
When sending in your permissions to IOP Publishing's journal or ebooks teams, ensure you:
Let the Editorial Assistant know if one/some of your figures do not need permission because they were published under an appropriate Creative Commons licence
Provide the licence type to the editorial assistant as well as the figure number to which it applies.
This will save your article from being unnecessarily delayed because permissions are flagged as ‘still required’.
