This textbook is for graduate students and young scientists, who are looking for an introduction to the physics and physical chemistry of crystal growth and nucleation phenomena.

This volume is a collection of the lectures presented at the NATO Advanced Study Institute "Interfacial Aspects of Phase Trans- formations", held in Erice (Sicily) in 198t.The Institute was the seventh course of the International School of Crystallography, es- tablished in the Center of Scientific Culture "Ettore Majorana" in 1974, with the guidance and inspiration of L. Riva di Sanseverino and A. Zichichi. The course organizers, R. Kern and myself, were advised and helped in developing the program, and in the choice of lecturers and participants, by R.F. Sekerka, F.
