LaTeX is really a layer cake and the bottom layer is Knuth's original 
primitive commands. The next layer is (most of) the plain tex format. This is 
incorporated into  the LaTeX format layer, next come optional LaTeX styles 
and add-on packages like pstricks. 

\def,  \edef etc. come from that bottom layer.  The TeXBook is a reliable, if 
somewhat hard to follow guide.  Beyond that canonical  work I use _TeX for 
the Impatient_ , A Beginners Book of TeX_ ,and _TeX by Topic_ in that order.  
Two of the three (Impatient and Topic) can be downloaded free. I ultimately 
bought a used paper copy of Impatient via Amazon Marketplace however because 
I use it so frequently and a ring binder is clumsy.  

I prefer plain tex, plain pdftex or Context to LaTeX or pdflatex.
