Smithsonian turns 177 years old!

The Smithsonian Institution—the world’s largest museum and research complex—includes 19 museums and galleries and the National Zoological Park. Currently, the total number of artifacts, works of art and natural science specimens in the Smithsonian’s collections is approximately 155 million. The bulk of this material—more than 145.8 million specimens and objects—is part of the National Museum of Natural History. In addition, Smithsonian collections include 162,000 cubic feet of archival material and 2.1 million library volumes.

As an opening summary, I thought I would re-post an overall round-up of the extent of the collections held by the institutions, the detail of the collections was correct at the time of publication back in 2018


The Smithsonian Institution—the world’s largest museum and research complex—includes 19 museums and galleries and the National Zoological Park. Currently, the total number of artifacts, works of art and natural science specimens in the Smithsonian’s collections is approximately 155 million. The bulk of this material—more than 145.8 million specimens and objects—is part of the National Museum of Natural History. In addition, Smithsonian collections include 162,000 cubic feet of archival material and 2.1 million library volumes.

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 space shuttle Discovery; from the ruby slippers featured in The Wizard of Oz to presidential paintings and memorabilia. Collection items 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 invertebrate zoology collection with more than 49.8 million specimens, ranging from corals and vent worms to parasites and squid.

Only a small portion of the Smithsonian’s collections (estimated at less than 1%) is on display in the museums at any given time. Many collections are acquired and solely used for research purposes utilized by scientists and scholars from all over the world. Whether they are acquired from the depths of the oceans, tropical rainforests, archaeological sites, everyday life, or even extra-terrestrially, Smithsonian collections are preserved and maintained for public exhibition, education, and study.

How Items Are Added to the Smithsonian Collections

The acquisition of collections is fundamental and critical to the mission and vitality of the Smithsonian. Most collection items are donated to the Smithsonian by individuals and private collectors or through transfers from federal agencies such as the National Aeronautics and Space Administration, the U.S. Postal Service and others. Thousands of items also come to the Smithsonian through field expeditions, bequests, purchases, and exchanges with other museums, and, in the case of living plants and animals, by propagation and birth. Collections must and do continuously grow to support the Smithsonian’s mission and programmatic goals. Ever-evolving collections ensure the ability of the Smithsonian to tell and share our nation’s continuing story in all its dimensions—across history, art, science, and culture. They contribute to global innovation and document the world’s forever changing cultural and scientific heritage from one generation to the next.

In doing so, the Smithsonian requires responsible, disciplined acquisition of collections based on stringent acquisition evaluation criteria. In order to provide responsible management of the collections, potential acquisitions undergo a rigorous selection and review process. The following criteria are considered during the review and evaluation of potential acquisitions: consistency with the museum’s mission, programmatic goals, and collections plan; the quality, size, physical condition, intellectual value, and significance of the collection item; the documentation of legal title and provenance; the potential for use in exhibition, education, and research; and the ability and costs to provide appropriate management, care and accessibility of the collection item, including conservation, long-term preservation, digitization, and storage. Because of this rigorous selection process, the Institution acquires only a small percentage of what is offered to the Smithsonian. Smithsonian turns 177 years old!
