Dr Ferri's Clinical Advisor '26 is, as always, a fabulous resource for any medical or NP practice!
Format: Hardcover
Excellent resource, as always from Dr Ferri. Well worth its generous weight to use a resource other than UptoDate once in a while. Besides, for us medical providers who have been in the calling many years, Ferri's Clinical Advisor 2026 is better at maintaining ones arm strength than lifting an iphone, plus safer and more accurate than the use of AI;)

You wont regret!
Format: Hardcover
Love! Love! LOVE! Everything in one book! Plus you get the e-version included as well! I am in NP school and the differential diagnosis book my school required is a joke! I took a chance on this book and am so glad I did! It's a big book! So plan on leaving it on your desk or tabletop, but at least youll have access to the ebook across your devices

Sketchy citations.
Format: Hardcover
Retired MD. Keeping up for the sake of family, friends and myself. I was looking for something like the “Medicine” book I had third year of med school. This is quite a bit more comprehensive. HOWEVER, the references/citations are hopelessly effed up. In the e book chapter on CHF, every reference I checked was about TRANSSEXUALISM in some way!! You authors/editors have some major work to do. I checked other chapters too. Seems even in Cirrhosis chapter the citations are to urology journals, total non sequiturs. HELP!!

Well-organised, concise and beautifully illustrated
Format: Hardcover, Format: Hardcover
The book can be described as concise, well-structured (being constant throughout its entirety), and quite graphic, aside from the prestigious drawings from Dr. Frank H. Netter, there's also real-life pictures included. The online resources are well used, and they're another tool in case someone want's a quick search instead of going to the index. I recommend this book for anyone who wants to have good knowledge of infectious diseases, without having to go to the more expensive authoritative source (Mandell, Douglas and Bennett's Principles and Practice of Infectious Diseases 9th Ed.), which is also mentioned in the preface.
