If you are publishing your thesis in whole or in part, there may be a few things to address.
Getting permission to use third party copyright material
If you'll be publishing substantial amounts of third party copyright material in your thesis, it's important to obtain clearance from any copyright owners in advance, so that you are able to do so without delay or complications.
Using insubstantial amounts of copyright material without needing to seek permission, e.g. in short quotations, is accepted academic practice, and also permitted under statutory exceptions for research in UK copyright law, provided the terms of the exception are fully met. Many of these exceptions apply only to non-commercial purposes such as teaching and examination. Academic publication is generally considered to be non-commercial from the author's perspective, as authors are not paid, but publishers may not always be covered under the exceptions as they are generally considered to be commercial entities, as they sell access to scholarly works. As a result, publishers may require authors to secure permissions or have rights departments which seek permissions.
Acknowledging third party work
You must make sure you have properly cited and acknowledged all third party content and contributions in your thesis to avoid allegations of academic misconduct, passing off, or plagiarism. Under UK copyright law, authors have certain moral rights in relation to their work. As an author, these also apply to you and your work. To respect moral rights, it's important to make sure that you have clearly acknowledged third party work using an appropriate form of credit.
Contractual obligations applying to your thesis
Where your thesis is sponsored and you have signed contractual agreements, you may need to check that publication will not breach those contracts leaving you or the University open to legal action.
Archiving your thesis in BURA is required under University regulations, so it is important where you publish your thesis in whole or in part, that you tell your publisher of this requirement to deposit your final thesis in the University's open access research archive.
As standard, many publishers ask you to transfer full copyright ownership to them, however, as a contract, it must be open to negotiation, and you should try to retain your copyright ownership if possible. You may be able to choose an open access option, giving the publisher a licence to publish. If publishing with a Brunel academic as co-author, you must ensure that the work is made open access under University policy. This gives your work maximum visibility and raises your profile, and that of the University.
It's possible for work to be placed under a temporary embargo where it will be published. However you should advise your publisher, that the thesis will be archived in BURA, when the embargo expires. See Submitting your thesis for more information on applying for an embargo.
