The Medical Book of Lists provides students and clinicians with a convenient white coat pocket-size source of potential differential diagnoses. With a wealth of over 310 lists and tables, readers can use Greenberger as a quick reference to jog their memory, organize their thoughts, clarify their intended approach, or double-check their work.
