Collections at NMNH

The Smithsonian Institution—the world’s largest museum and research complex—includes 19 museums and galleries and the National Zoological Park. The total number of artifacts, works of art and specimens in the Smithsonian’s collections is estimated at 156 million, of which 145 million are scientific specimens at the National Museum of Natural History.

Among the vast collections are irreplaceable national icons, examples of everyday life and scientific material vital to the study of the world’s scientific and cultural heritage. The objects in Smithsonian collections range from insects and meteorites to locomotives and spacecraft. The scope is staggering—from a magnificent collection of ancient Chinese bronzes to the Star-Spangled Banner; from a 3.5 billion-year-old fossil to the Apollo lunar landing module; from the ruby slippers featured in The Wizard of Oz to presidential paintings and memorabilia. Collection objects vary in size, from the Concorde at 202 feet to the Fairfly wasp at .0067 of an inch. The largest single collection is Natural History’s paleobiology collection with more than 4.26 million fossil specimens, ranging from dinosaur skeletons to microscopic foraminifera.

Only a small portion of the Smithsonian’s collections (estimated at less than 2 percent) is on display in the museums at any given time. Many collections are used by researchers from all over the world. They come to the museums or to the Museum Support Center, which houses most of the Natural History collections and labs.

How Artifacts Are Added to the Smithsonian Collections

Most artifacts are donated to the Smithsonian by individuals, private collectors and federal agencies such as NASA, the U.S. Postal Service and others. Thousands of items also come to the Smithsonian through field expeditions, bequests, purchases, exchanges with other museums, and, in the case of living plants and animals, by birth and propagation. Museum curators and directors seek objects that are appropriate to their particular collections, authentic, and of historic, artistic or scientific significance.

Curators also consider the size of an object, its exhibit potential—physical condition, amount of work required to prepare it for display—and its “readability” (whether a visitor can understand the object by looking at it). For additions to the scientific or research collections, curators seek specimens that fill gaps in the existing collections.
After the decision is made to officially accept an artifact, it is given an accession number. Catalog information about each item—what it is, accession number, donor’s name, date, condition, provenance, historical and scientific context, and location at the Smithsonian—is recorded in the particular department so that staff members and researchers will have easy access to the information.

Most objects that are formally “accessioned” become part of the Smithsonian’s permanent collections, held in trust for the American people. However, on some occasions, objects are “deaccessioned” or removed from the collections following a careful review process by curators, directors and, where appropriate, by board members. These deaccessioned objects may be transferred to other organizations such as museums or other appropriate nonprofit organizations.
