Yes, you are able to ask for PhD theses on Ethos to be digitised for free.

All you have to do is to create an account, choose the title you would like to be digitised, select 'Download' in the 'Download and delivery options' page (this is the only free option, and it means you will be sent a download, not a paper copy of the thesis).

You will be notified by email once the dissertation has been digitised. Then, log back into Ethos and retrieve the download.
