So...I wrote my thesis on the same topic as my dissertation. My thesis was not published.

Can I use "basically" the same literature review in my thesis as I did in my dissertation? Parts would be added as specific to the dissertation but some parts would be verbatim.

Taking into account that a PhD literature review can be longer than the dissertation itself, I would assume that you need to add a substantial amount of work.

But again, every PhD is different. Maybe you have a very limited topic with very few publications available, so you literature review is really limited.
