The USDA Crop Fiber Research Collection contains documents relating to more than 300 genera of plants used for fiber. The materials cover the subject of natural plant fiber crops other than cotton, and include information on cordage, textiles, and miscellaneous fibers as well as the products made from them. There are reprints and photocopies of fiber articles with an extensive card index, manuscripts, foreign and domestic publications, promotional brochures, reports, newspaper clippings, glass and acetate negatives, slides, black and white photographs, and fiber specimens.
