Presentation on the history of The Book Collector at the Caxton Club, Chicago.
Founded in 1884, the Grolier Club is America’s oldest and largest society for bibliophiles and enthusiasts in the graphic arts. Named for Jean Grolier (1489/90-1565), the Renaissance collector renowned for sharing his library with friends, the Club’s objective is to promote “the study, collecting, and appreciation of books and works on paper.” Through the concerted efforts of an international network of over eight hundred men and women—book and print collectors, antiquarian book dealers, librarians, designers, fine printers, binders, and other artisans—the Grolier Club pursues this mission through its library, its public exhibitions and lectures, and its long and distinguished series of publications. The Grolier Club has published or sponsored almost 500 books and exhibition catalogues - some of them now the standard references in their fields - on such subjects as photography, William Blake, Mayan writing, Albrecht Dürer's alphabet book, and the well-known "Grolier Hundred" selections in literature, science, and medicine.
