"Inwood provides a very good bibliography of primary and secondary sources, an essay on Heidegger's idiosyncratic language, a general index and another for "foreign words and expressions," and the dictionary itself....The dictionary consists of brief essays on concepts and concept clusters and on four of Heidegger's major works, all as clear as possible and very much to the point...One of the most intelligible books in the English about this thinker." J.M. Perreault, Choice.
