I work in research, only moonlighting clinically part time, doing chart reviews. I don't always remember all of the finer details associated with some diagnoses. This book contains enormously useful information in a condensed format -- both in its articulation and physical shape which fits in a lab coat pocket. I find it to be a great quick reference, with appropriate uses of tables and algorithms to quickly refresh one's memory on the spot. literature references were included for each section which isn't always the case for other books of this type.
