Of those pictured, I only have Differential Geometry (haven't read yet), and Geometry, Relativity and the Fourth Dimension.

Are Dover books the best? I don't know, but they have often have good graphic design on their covers, and they are cheap.

I acquired 'Advanced Engineering Mathematics' by Erwin Kreyszig for like $11. It covers all kinds of stuff, some of which didn't stick all that well, and some which I never got to go over in my classes. There's some graph theory! Yay!

I was gifted 'The Visual Display of Quantitative Information' by Edward R Tufte at Christmas, and I finally got around to reading it this afternoon. I promise I'll only share the cool parts.
