Copernicus’s complete works are collected in English translation in On the Revolutions, ed. and trans. by Edward Rosen (1978, reissued 1992); and Minor Works, ed. and trans. by Edward Rosen and Erna Hilfstein (1985, reissued 1992).
Biographies include Jack Repcheck, Copernicus’ Secret: How the Scientific Revolution Began (2007); and Dava Sobel, A More Perfect Heaven: How Copernicus Revolutionized the Cosmos (2011), both for the general reader; and the more scholarly biography in N.M. Swerdlow and O. Neugebauer, Mathematical Astronomy in Copernicus’s De Revolutionibus, vol. 1 (1984).
A general overview of Copernicus’s ideas and their impact is presented in Thomas S. Kuhn, The Copernican Revolution: Planetary Astronomy in the Development of Western Thought (1957, reissued 1985). Robert S. Westman, “Two Cultures or One? A Second Look at Kuhn’s The Copernican Revolution,” Isis, 85:79–115 (March 1994), provides a critical reevaluation with a more recent bibliography. The series Studia Copernicana (1970– ), which offers a rich collection of scholarly studies on aspects of Copernicus’s life, work, and later reception; and Robert S. Westman (ed.), The Copernican Achievement (1975), are recommended for advanced study. Owen Gingerich, The Great Copernicus Chase and Other Adventures in Astronomical History (1992), and The Eye of Heaven: Ptolemy, Copernicus, Kepler (1993); and Robert S. Westman, The Copernican Question: Prognostication, Skepticism, and Celestial Order (2011), are useful for scholarly and general readers. J.L.E. Dreyer, A History of Astronomy from Thales to Kepler, 2nd ed. (1953), is an older but still useful work; it can be supplemented by René Taton and Curtis Wilson (eds.), Planetary Astronomy from the Renaissance to the Rise of Astrophysics, Part A: Tycho Brahe to Newton (1989). Two challenging interpretations are Hans Blumenberg, The Genesis of the Copernican World (1987; originally published in German, 1975); and Fernand Hallyn, The Poetic Structure of the World: Copernicus and Kepler (1990; originally published in French, 1987).
