For efficient service, please read through the following list and contact the appropriate office directly.
The Smithsonian acquires thousands of objects and specimens each year for its collection holdings through donation, bequest, purchase, exchange, and field collecting. Each museum and curatorial department decides on a case-by-case basis which objects to add to its collections. Donations are accepted only when the item truly complements the collection. We also consider whether we can properly care for an intended donation, as our collections are held in trust for the American people.
If you are interested in donating objects to one of the following Smithsonian museums, please visit the appropriate webpage:

- a description of your object or an inventory of your collection,
- a few images of the objects you wish to donate included as attachments (our mail-processing program strips out embedded email images),
- as much provenance information as you have (how long you’ve owned the object; when, where, and how you received it; its origins; etc.),
- a brief explanation of why you think your object belongs in the Smithsonian (its historical, cultural, artistic, or scientific significance), and
- an indication of which Smithsonian museum or office you think should receive it.
The Office of Visitor Services will forward your complete donation offer in a single email to the appropriate curatorial staff, who will contact you only if they are interested in pursuing your offer. The Office of Visitor Services is not informed of such decisions.
Under no circumstances should you send us your object without prior written curatorial approval.
The Smithsonian holds nearly 154 million objects in its collections, distributed among its 19 museums, the National Zoo, libraries, research centers, and storage facilities. Many artifacts are donated to the Smithsonian by individuals, private collectors, and federal agencies; others come to the collections through field expeditions, bequests, exchanges with other museums and organizations, and purchases.
Only a small percentage of the Smithsonian’s vast holdings are on view. Many artifacts not on display are stored in collection study areas in the museums and are available to researchers by appointment. Air- and spacecraft are conserved and stored at the Steven F. Udvar-Hazy Center, part of the National Air and Space Museum, in Chantilly, Virginia. Other research collections are housed in Landover and Suitland, Maryland, facilities.
Most of our collections have been cataloged in our Collections database. If you don’t find the object you are interested in listed there, please send as much information about the object as you have to firstname.lastname@example.org; such information as a complete description of the item, its history, how and when it came to the Smithsonian, who donated it, and the museum or facility to which it was donated can help us refer your inquiry to the appropriate collections staff.
Some museums and units may be contacted directly. To either conduct research or inquire about a collection, either send a detailed email or follow instructions at any of the following:
