This casebook is tightly and coherently structured, intelligently distilled, and clearly contextualized. It explores the complex issues surrounding protection of intellectual creativity under U.S. copyright law while ensuring that both student and professor always maintain an understanding of how doctrinal elements relate to the whole. The book is perfect for those students who have struggled with dense notes and opaque explanations, professors who have labored through cumbersome or poorly ordered texts, or for new teachers who need a clear pedagogic template complete with both substantive doctrine and highly instructive cases. The third edition expands upon the first two and brings the material up to date while retaining its eminently teachable structure.
