"Concise and accurate, The Little Black Book of Primary Care cuts right to the chase and gives the provider the information to diagnose and treat the thousands of conditions the busy practitioner can encounter.   It’s easy to use format includes not only diagnostic and treatment pearls but each subject is referenced for more detailed study.   This is the book I turned to on a daily basis for practicing in rural Alaska."

"An invaluable resource for the medical student or intern who needs a concise and logical breakdown of medical conditions, and comprehensive enough to expand one's understanding and trigger recall of pertinent relative information."

"There is nothing ‘little’ about Dr. Onion’s book.  For primary care internal medicine, it is complete, from its lists of differential diagnoses to its most recent references to the literature.  I use it to round out consults, to find references for housestaff, and to fill in my own gaps in medical knowledge.  If your favorite textbook of internal medicine is champagne, then Dr. Onion’s book is its cognac: a very fine distillation of our discipline."

"I am a traveling family practice doctor, currently working in Antarctica for the summer season. Our medical library here is very limited and our internet connection unreliable. Fortunately, I have Dr. Onion's  The Little Black Book of Primary Care. This comprehensive yet concise and reliable resource has proven very valuable and has helped me in both in-patient and out-patient situations."

--Kimberly Merris, MD, MPH, Family Practitioner

“This organized little black book contains a wealth of information important in day-to-day care of patients in the primary care setting. The information, nicely distilled by medical specialty, is easy to follow and find.”
