National Museum of American History"Our collections span centuries and include objects related to protest and politics, medicine and psychology, love and marriage, sports and entertainment, and more. Sometimes, curators and archivists collected objects for a specific reason that later turned out to have LGBTQ+ connections... The museum is continually adding to and mining our existing resources in order to better understand evolving and overlapping identities such as lesbian, gay, bi-sexual, transgender, queer, transsexual, transvestite, mahu, homosexual, fluid, invert, urning, third sex, two sex, gender-bender, sapphist, hijra, friend of Dorothy, drag queen/king, and many other experiences."
