The Legacy of the National Library of Medicine
The history of the National Library of Medicine mirrors the progress of medicine itself—a path of constant growth, resilience, and adaptation. What began as a modest collection has become the world’s leading hub for biomedical knowledge.
Early Foundations
The story began in 1836, when a small medical library was created within the U.S. Army Surgeon General’s Office. At first, its purpose was limited: providing doctors in the military with medical texts and resources to improve healthcare for soldiers. Over time, however, as the practice of medicine became more complex and the need for structured knowledge increased, the library began to expand its reach.
A Shift to National Significance
By the early 20th century, the library’s growing collection made it clear that it had moved far beyond its military roots. In 1956, it was officially transferred to the National Institutes of Health (NIH) and given the name National Library of Medicine. This transition marked its evolution from a military archive into a national institution with global influence.
Preserving Knowledge, Inspiring Progress
Today, the National Library of Medicine holds millions of items—ranging from books, manuscripts, and journals to photographs, archives, and digital resources. It not only protects the historical record of medicine but also ensures that current research and discoveries remain accessible to guide the future of healthcare.
The journey of the National Library of Medicine, from a modest government library to a global leader in biomedical information, is a reflection of medicine’s own trajectory. Constantly adapting and expanding, it continues to ensure that the wisdom of the past and the discoveries of the present are available to shape tomorrow’s healthcare solutions.
