Handbook of Gifted Education (3rd Edition) - Nicholas Colangelo, Gary A. Davis
I read this book because it was required reading in a class I was taking. Some of the essays were better than others, and several merely repeated earlier ideas so that the themes became repetitive after a time. I garnered some useful information from it, however, and instead of selling back the book, I am going to keep it on my professional reading shelf as a reference for future use.
