Welcome to NLM!

Join us as we introduce you to the center of biomedical informatics and computational biology at NIH and the world’s largest biomedical library!

Welcome to the fascinating world of the National Library of Medicine (NLM)! NLM is not your typical library; we curate the world’s richest collections of historical material from the 11th century to the most cutting-edge data of the 21st century. The oldest item in the collection—an Arabic manuscript on digestive diseases—dates back to 1094.

NLM pioneers open science and data science initiatives to collect, organize, and disseminate the world’s health information. We serve researchers, publishers, librarians, educators/trainers, healthcare professionals, and members of the public.

NLM has both a Division of Intramural Research (DIR) and a Division of Extramural Programs (EP). DIR develops and applies computational approaches to a broad range of problems in biomedicine, molecular biology, and health. It also provides training and research opportunities for future computational health and bioinformatics leaders. EP offers grants for research projects and research training in biomedical informatics and data science.

NLM’s open science tools and resources enable clinical testing labs, researchers, and citizen science to engage communities in addressing societal needs and accelerating biomedical science, technology, and innovation.

Enjoy exploring some of what the library has to offer. Meet our researchers, get familiar with our outreach programs, and revisit some of our most memorable exhibitions. Explore our popular tools like ClinicalTrials.gov which lists more than 375,000 research studies from all 50 states and 220 countries and PubMed with more than 36 million citations for biomedical literature which are accessed 15 million times every day.
