Chronological Catalog of Frege's Work

This Bibliography was compiled and cross-checked with the help of Bynum [1972], Beaney [1997], Hermes [1969], and Angelelli [1967]. Sources were checked, errors were eliminated, and page numbers were added whenever possible. Please notify the author if you find any remaining errors. No citations to Frege's letters are compiled. These may be found in Gabriel et al. [1976] and Janik [1989], many of which were translated in Gabriel et al. [1980] and Woodward [1967].
