            Johannes Kepler's Astronomia Nova, published in 1609, was the oldest book available in the archives. It contains the results of Kepler's ten-year-long investigation of the motion of Mars. Where previous astronomers had relied on geometric models to explain the observed positions of the planets, Kepler discovered physical causes for planetary motion. Before Kepler, Nicolaus Copernicus proposed in 1543 that the Earth and other planets orbit the Sun. Kepler was the first astronomer to prove this conjecture with rigorous scientific arguments. This Volume has 336 pages and is in fairly good condition.

            The book "An Elementary Treatise on the Lunar Theory with a Brief Sketch of the History of the Problem" was written by Hugh Godfray. Hugh Godfray (c1821-1877) first published his treatise in 1853, a year after he graduated from St. John’s College. Lunar theory would become central to George Darwin’s work, and he went on to form crucial theories regarding lunar acceleration, earth retardation, the earth-moon system, and the genesis of the moon. It was published in 1987
