Sorry - meant to say that I wouldn't be able to include the PhD theses review in my lit review for this conference paper!! Sorry!! :$

I am in 1st year and trying to write my first conference paper which is on my lit review. Supervisor said that I have not read all the literature, which I accept, but then threw in a curveball that I should now look through all PhD theses in my area! Not going to happen for the purposes of this lit review - so how do I put it that I am not saying that I have read everything but that I have read everything that I reference in my paper or that I have found - I am worried about questions at the conference that start along that theme!!

Any tips please??

Thx!
