Much like the pocket medicine book we all love, this book contains all of the high-yield, easily-readable information you need to know to take care of your patients as a House Officer. While I have piles of medical books collecting dust, this is one of the four books I ACTUALLY use and one of the two books I keep in my pocket. It's weak in neonatology, but it makes up for it in PICU material. If it only had a few pages dedicated to medication dosing, I'd be leaving my Harriet at home. If I had to pick one book to carry with me, this would be it.
