Query: ASCII texts and negation

I am writing an undergraduate thesis on Greek negation, and am interested 
in any available material on these phenomena.  I am currently working with
an ASCII version of the homeric texts and am searching out an ASCII 
NT-Greek text as well.  Also, any information regarding the availablity of
such a thing would be helpful although I think I'm half on my way to 
getting that already.  Regarding negation phenomena, I'm especially 
interested in any historical works on such things and any discussions 
on quantifier and negation "relationships".  This is a linguistics thesis 
so any degree of technicality is alright with me.

Thanks in advance,
Chloe Mills
