Preface

These notes for a graduate course in set theory are on their way to becoming a book. They originated as handwritten notes in a course at the University of Toronto given by Prof. William Weiss. Cynthia Church produced the first electronic copy in December 2002. James Talmage Adams produced the copy here in February 2005. Chapters 1 to 9 are close to final form. Chapters 10, 11, and 12 are quite readable, but should not be considered as a final draft. One more chapter will be added.
