Go-go boys in gold lamé shirts, sequin-bedecked grandmothers and the freshest-looking librarians you’ve ever met made up the unlikely crowd dancing into the night at the Library of Congress’s first after-hours party on Saturday.

Billed as a celebration of the history of dicso, “Bibliodiscotheque” featured a symposium hosted by singer Gloria Gaynor and Librarian of Congress Carla Hayden.

The evening, which culminated in a performance by Gaynor and, of course, plenty of pointy-fingered dance moves against the marble-columned backdrop, was a collaboration between the Library of Congress and the cultural-media company Brightest Young Things.
