National Collections

The National Collections are central to the Smithsonian’s core activities of scholarship, discovery, exhibition, and education. They are a vital resource, accessed by millions of visitors and researchers exploring subjects from aeronautics to zoology. The National Collections have a significant role in addressing scientific and societal issues in the 21st century. Collections acquired a century or more ago are used today to address climate change, the spread of invasive species, and the loss of biological and cultural diversity and their impact on global ecosystems and cultures. Smithsonian collections also define our national identity by documenting our history, diversity, and values. Digitizing the collections makes access to them possible anywhere, anytime for research, education, creativity, and enjoyment.

Mass digitization, Digitization Program Office

The extent to which the Smithsonian has digitized its collections is a measure of both public access and good collections management. Digitization involves creation of a digital record and digital images or other digital surrogates such as 3D data, audio, or video. Our goal is to have all holdings described by digital records and a prioritized subset of the National Collections represented by digital images or other digital surrogates. Digital assets are available online at the Collections Search Center and other Smithsonian websites. To learn more, visit the Digitization Program Office.

Collections stewardship—the development, documentation, management, preservation, and use of collections—is not a single process or procedure. Collections care, storage, and digitization represent a continuum of activities that directly affect the Smithsonian’s ability to make collections available to scholars and the public worldwide. Meeting established standards and sound management practices for the care of collections is measured by the state of object preservation, condition of facilities housing collections, quality of storage equipment, and ease of locating and retrieving collections.

Lending and borrowing collection items for public exhibition, research, and education is an integral part of the Smithsonian’s mission. Loans between Smithsonian collecting units, as well as loans to and from other educational and scientific organizations are fundamental to the Institution’s programs. The number of Smithsonian collections on loan to other organizations is a measure of public outreach.
