The Many Realms of King Arthur exhibit explored the legend of King Arthur from its origins in the Middle Ages to its 20th Century representations. The exhibit was based on the Arthuriana collections of Chicago's Newberry Library and the New York Public Library. The ALA Public Programs Office and the Newberry Library collaborated in producing the exhibition with funding from the National Endowment for the Humanities (NEH).
Included in the exhibit were illustrations of medieval manuscripts, engravings, paintings, books, films, musicals, comic books and other genres that tell the story of Arthur, Queen Guinevere, Lancelot, and the knights and ladies of the Round Table. The exhibition offered an opportunity for a variety of programming designed to stimulate public discussion about the universal issues addressed by the legend of Arthur, such as loyalty and duty, idealism, codes of morality, just warfare and love.
