This is a comprehensive and indispensable book for all serious anglophone students of Heidegger. Based upon but not limited to the Gesamtausgabe, its 261 entries provide bibliographic details of Heidegger's works in over 400 English versions. But Groth has put together more than an enumeration of titles. Among his other useful sections are: An alphabetical list of all the translators and what they have translated. The up-to-date contents of the Gesamtausgabe. Lists of videos, audio recordings, and audiobooks in German and English. Heidegger's texts which have been translated into English, listed both by title and by date of composition. Heidegger's lecture courses and seminars, listed by dates of composition, presentation, and publication. We can learn quite a bit about Heidegger just by scanning these chronologies, discerning a genetic progression in his thought, seeing not only what interests English translators, but also what interested him at the various stages of his career, and perhaps even gathering evidence to pinpoint the "turning(s)." Extensive cross-references enable easy movement among all categories.
