Very useful reference book- includes tools, part breakdowns of lighting instruments (including my personal nemesis, the Ellipsoidal Reflector Spotlight), color theory, and basic stage/set construction. Some of the technical issues may be considered out-of-date in professional circles, but if you're in a theatre that still uses older instruments, this book is as valuable as the day you had to buy it for your set design class.
