Special message to researchers: While the Smithsonian National Museum of Natural History exhibition spaces will partially open to the public on June 18th, our collections remain closed to most staff and all researchers, and the museum’s COVID-19 loan moratorium remains in effect. Currently, there is no capacity to accommodate collections activities including visits, image requests, loans, and shipments. While there is no current date set for when on-site collections activities will resume, we will update as soon as this changes.
Our Collections
Eminent scientists, specimens, books and papers, microscopes, and sophisticated computer systems: Welcome to the realm of NMNH Research and Collections. In this university-like atmosphere, scientists delve deep into the history of our planet and the processes and peoples that shape it today.
Museum explorers travel to ocean depths, the peaks of the Andes, Africa's Rift Valley, the rainforests of South America, and the deserts of Central Asia. Perhaps even to a field site or research institution in your own state, territory or country. In each area, researchers collect specimens: fossils, minerals, and rocks, plants and animals, tools and artworks. Collections care professionals have meticulously preserved, labeled, cataloged, and organized items of this kind for more than 150 years. 
Taken together, the NMNH collections form the largest, most comprehensive natural history collection in the world. By comparing items gathered in different eras and regions, scientists learn how our world has varied across time and space.
145 million items in our ever-growing collections!
