NL noob required reading list plz.

[SofaCoach]

I've been playing micro-small limits online for about the last 18 months and winning at a decent rate up to the $3/6 level, but I want to expand my horizons to the NL game. I've just started playing the Party $10-1 SNG's. When learning/refining my limit game I read Lee Jones LLHE and Millers SSHE. What books would be best for learning the NL game? I saw in another post a recommendation for Harringtons I and II. Are those two different books? What others do you all think would be good? (super system?)
