How do I protect my unpublished phd work (which i am planning on publishing soon)? I am conducting expert interviews and I will have to send parts of my work to them for validation. But, how to ensure that they don't copy it or use it in their work before I publish it?
In most countries your work is copyrighted when you create it. That is simple. The other question you need to address yourself is, why would folks you have contacted steal your work? This is a fear many people have, but almost never actually happens. Get over that fear.
