Query: A must have for my office

I am a high school guidance counselor working with college applications and college seeking students at a large college prep high school. In the true sense of the word, "Rugg's" makes my job a lot easier. He is able to crystalize information regarding college majors, specialities, entrance requirements, and geographic elements into easy and obtainable informational bits. I can obtain school names for kids interested in certain area of study. The research for the details is still left to me, but Rugg's quick finding book allows me to gather in the details through research of my own. I would not be able to even begin to know where to look in many cases without this book. Considering that there are some 3700 colleges and universities in the US, he does a remarkable job of sifting through what you need to know to begin your research.
