When disseminating research and scholarly outputs it is important to take account of copyright legislation, and ensure that you work within the licences or conditions imposed by publishers and funding agencies. This applies to the production of all scholarly works including PhD theses, articles, books and chapters.
When producing something for publication, the publisher is will usually ask for evidence that you have permissions from the copyright holder of any third party copyright materials you have used in your work. This will include any diagrams, maps, photographs or images. They may also ask you to sign an indemnity form which removes any liability from them.
Instances where you do not need copyright are:
The Copyright of your doctoral thesis usually belongs to you as the researcher and author of the work, however, you may wish to use third party works in your thesis, including illustrations, graphs or photographs.
If you wish to publish your thesis, you must obtain permission from the rights holder to use these materials in your thesis, and you should be aware, that publication also includes making a digital copy available through a repository such as OARS.
If you are unable to secure the permissions of the known copyright holder, third party materials should be redacted from the published document. It is good practice to seek these permissions prior to submission.
Before you publish any work containing any third party copyright materials you must have permission from the rights holder to reuse their materials in your work.
