 This volume honors Herb Clemens and his contributions to algebraic geometry. The exceptional gathering of mathematicians at the symposium attest to his remarkable career. Papers in the book address topics in which Clemens has been active: the geometry of threefolds, enumerative geometry, Hodge theory, and higherorder methods for attacking deformation problems. The volume is suitable for graduate students and research mathematicians interested in algebraic geometry.
