Permissions for reproducing published material in your article

If your article makes use of any previously published material (including figures/diagrams, or short extracts, or content taken from websites) then you must first obtain the written permission of the copyright owner. The copyright owner is usually the publisher (for material taken from journal or proceedings articles), website owner/company (for material taken from websites) or the author or their employer (if the work is unpublished). Some publishers will also require that you seek the permission of the original author (you will need to check the terms of the publisher’s permission).

We ask you to submit written evidence:


That all necessary permissions have been obtained by providing the actual written permission granted by the copyright owner, or


That permission is not required, e.g. where the material is available under one of the Creative Commons licences which allow commercial reuse and suits the purpose for which you want to reuse the content.

We do not obtain permissions on your behalf. It is your responsibility as the author of the article to ensure that all required permissions have been obtained in writing and any permission fee paid in full (if the copyright owner charges a fee for reuse).

IOP is a signatory to the STM Permissions Guidelines. This benefits you because if you are reusing content from another STM signatory publisher, you are usually allowed to use up to three figures in another article published by an STM signatory publisher free of charge (provided you are not adapting/changing the figure). If the STM signatory publisher has ticked the second column ‘Notification required’ in the list of signatory publishers then you must still obtain permission but you should receive the permission for free. For more information, please see the STM Permissions Guidelines page.

Please refer to this page for a useful guide on how to obtain permission.
