Books and Pamphlets

The Willoughby collection is divided into three series and housed in four document boxes. It is comprised mostly of drafts of literary works, contained in the Literary Productions series, as well as correspondence, mostly relating to his librarian work, and miscellaneous other materials. The materials date from 1928 to 1965, with the majority of materials dating from the 1940s and 1950s.

The collection includes correspondence, speeches, essays, notebooks, bills, printed materials, and notes on debates and other such topics as the Light Street Institute and the Washington Temperance Society. The collection spans three main time periods in Zug's life: his enrollment at Dickinson College from 1836 until 1839, his formation of and participation in the Light Street Institute from 1839 until 1840, and his involvement in the Washington Temperance Society from 1840 to 1842. Other time periods are included, but not as extensively. The collection contains no large gaps in documentation. One item of interest is a manuscript entitled "An Old Bachellor's[sic] Mountain Musings." The opening line of the piece, which is not dated, states that the author, presumably Zug, is forty-seven years old. However, this is not possible, as Zug died on September 5, 1843, at the age of twenty-five.
