The Joseph Valentine Kopycinski Collection, also referred to as the JVK Collection, is composed of over eight hundred rare volumes. The books include Greek and Roman classics, with strong holdings in American history and theology, as well as rare editions of poetry ranging from Robert Burns to Robert Creeley. It also includes graphic artists such as Rockwell Kent and Francis Job "Frank" Short, oversized art books, temperance pamphlets, sheet music, hymnals, and children's books. One of the highlights of the JVK Collection is a set of Hough’s fourteen volume “American Woods” (1903-1928). Housed in clasped slipcases, these books contain the exhaustive dendrological nomenclature of the day while the “pages” are composed of actual wood specimens of over 1,000 American trees, thinly sliced in transverse, radial, and tangential sections so that every page of each edition is a one of a kind. The Collection also includes Kopycinski's American West Collection, yet to be cataloged.
