The Merck Manual of Diagnosis and Therapy (Medical Reference)

/Home/Hematology - Publications

In 1899, the American drug manufacturer Merck & Co. first published a small book titled Merck's Manual of the Materia Medica. It was meant as an aid to physicians and pharmacists, reminding doctors that “Memory is treacherous.” Compact in size, easy to use, and comprehensive, The Merck Manual (as it was later known) became a favorite of those involved in medical care and others in need of a medical reference. Even Albert Schweitzer carried a copy to Africa in 1913, and Admiral Byrd carried a copy to the South Pole in 1929.

By the 1980s, the book had become the world's largest selling medical text and was translated into more than a dozen languages. While the name of the parent company has changed somewhat over the years, the book's name has remained constant, known officially as The Merck Manual of Diagnosis and Therapy but usually referred to as The Merck Manual and sometimes “The Merck.”

In 1990, the editors of The Merck Manual introduced The Merck Manual of Geriatrics. This new book quickly became the best-selling textbook of geriatric medicine, providing specific and comprehensive information on the care of older people. The 3rd edition was published in five languages. The creation of this book reflects Merck's commitment to the world's aging population and the company's desire to improve geriatric care globally.

In 1997, The Merck Manual of Medical Information–Home Edition was published. In this revolutionary book, the editors translated the complex medical information in The Merck Manual into plain language, producing a book meant for all those people interested in medical care who did not have a medical degree. The book received critical acclaim and sold over 2 million copies. The Second Home Edition was released in 2003 and continued Merck's commitment to providing comprehensive, understandable medical information to all people.

The Merck Manual of Health & Aging, published in 2004, continued Merck's commitment to education and geriatric care, providing information on aging and the care of older people in words understandable by the lay public.
