Poker books

[DaFrench1]

I just got loads of books that are going to keep me busy for a while. With the multi-volume books (like Harrington on Holdem), Do I need to read all 4 volumes? or is the last one just the most updated version and I can stick with that?

Harrington on Hold'em 1 and 2 are seperate books. The second book picks up right where the 1st one leaves off. The 3rd Harrington Book is a workbook from my understanding to reinforce the concepts from 1 and 2. I haven't checked out the work book but really liked 1 and 2. Those are the only books I have read so far.
