The Wilcox Collection is one of the largest assemblages of US left and right wing political literature in this country. Established in 1965, the collection has grown steadily to include coverage of more than 10,000 individuals and organizations. The bulk of the collection covers 1960 to the present and is comprised of nearly 10,000 books, pamphlets and periodicals, 800 audio tapes, 73 linear feet of manuscript materials and more than 100,000 pieces of ephemera including flyers, brochures, mailings, clippings and bumper stickers. Laird Wilcox, the originator of the collection, continues to make regular donations and additions are being actively sought.
