The Manuals are known as Merck Manuals in the United States and Canada and as MSD Manuals elsewhere. The homepage states that the Manuals are available for free in digital form in multiple languages. The first edition was published in 1899.
Each version has its own content focus. The professional version includes clinical calculators, case studies and quizzes.
