Top Home Medical Reference Book

The world's best-selling home medical reference book is Merck Manual Consumer Version. It's in full text online, and it's completely free. There are many positives to having a collection of print reference books in your home. But what's great about digital is the real-time updates and extras you can't get from a paper version.

We are continually updating our content and publishing it online as soon as it is ready, so we make no distinction among “editions.” Robert S. Porter, MD, Editor-in-Chief, The Merck Manuals
