Reading material on ToZ

[En Haradren Amlug]

Hey, I remember that i found once on the ToZ site links to some PDF formats of a few (i think 3 or 4) books that HP Pythia recomended reading. But i cant remember where it was. does any1 know where they are? i didnt get to finish reading them b4 my computer died and i had to get a new 1.

thanks.

Ave Zeus!
