Purpose: The purpose of the Museum Universe Data File is to provide a list of known museums and related organizations in the United States.
Coverage: The Museum Universe Data File (MUDF) contains information about over 35,000 museums and related organizations in the United States including aquariums, arboretums, botanical gardens, art museums, children’s museums, general museums, historic houses and sites, history museums, nature centers, natural history and anthropology museums, planetariums, science and technology centers, specialized museums, and zoological parks.
Content: The Museum Universe Data File (MUDF) contains basic identifying information of known museums and related organizations in the United States.
Frequency: Data is reviewed and updated twice annually.
Methods: The data in this file is collected and aggregated from a variety of sources including IMLS administrative data and records, Internal Revenue Service (IRS) non-profit data (e.g., 990, 990-EZ, 990-N), grantee lists from private foundations and data obtained from third party commercial vendors.
Use: These collected data are useful to researchers, journalists, the public, and policymakers at the federal, state, and local levels. These data are used by federal, state and local officials, professional associations, and local practitioners for planning, evaluation, and policy making.
How will the data file be maintained?
This database will undergo periodic review and updates. IMLS encourages the public to examine the database and to contact the IMLS research staff if there are institutions that should be added or entries that should be deleted. IMLS is accepting comments at email@example.com.
