The Editors are pleased to present the 21st edition of Harrison’s Principles of
Internal Medicine. This 21st edition is a true landmark in medicine, spanning
71 years and multiple generations of trainees and practicing clinicians. While
medicine and medical education have evolved, readers will appreciate how
this classic textbook has retained enduring features that have distinguished
it among medical texts—a sharp focus on the clinical presentation of disease,
expert in-depth summaries of pathophysiology and treatment, and highlights
of emerging frontiers of science and medicine. Indeed, Harrison’s retains its
conviction that, in the profession of medicine, we are all perpetual students
with lifelong learning as our common goal.
This edition has been modified extensively in its structure as well as its content
and offers a more consistently standardized format for each disease chapter.
The authors and editors have curated rigorously and synthesized the vast amount
of information that comprises general internal medicine—and each of the major
specialties—into a highly readable and informative two-volume book. Readers
will appreciate the concise writing style and substantive quality that have always
characterized Harrison’s. This book has a sharp focus on essential information
with a goal of providing clear and definitive answers to clinical questions.
