Erratum

p179, Section 4. I should have noted that the method of construction of the Jacobian variety in this section was suggested to me at the conference by Janos Kollar.

p194, 5b. Should read: \[ \cdots\overset{\Phi}{\rightarrow}\cdots\overset{\Psi}{\rightarrow}% \] (the arrows were omitted).

p198, Theorem 10.1. This is true also over finite fields (Gabber, O. On space filling curves and Albanese varieties. Geom. Funct. Anal. 11 (2001), no. 6, 1192--1200; Poonen, Bjorn, Bertini theorems over finite fields. Ann. of Math. (2) 160 (2004), no. 3, 1099--1127.)

p200, 15b. Should read: exist a finite resolution (insert finite).
