Explore the Vast Scientific Collections of D.C.’s National Museum of Natural History Paired with Respective Experts

Carefully arranged within thousands of drawers, flat files, and shelving units are the collections of the National Museum of Natural History
(NMNH) which together comprise 90% of the Smithsonian’s collections.
Found in these material assortments are the reference objects that help
scientists, researchers, and museum curators understand our planet—from
solid earth fragments to biological material and cultural objects from
civilizations long diseased.
