This paper addresses the literary canon surrounding the nineteenth century philosopher Friedrich Nietzsche, in order to inform philosophy librarians as to the nature of the particular body of literature. Using the "Philosopher's Index" database to locate all the Nietzschean literature published between 1986 and 1995, defining characteristics of this body were identified. Descriptive bibliometric analysis was used to identify principal authors, language of creation, the journals in which Nietzschean literature has most frequently appeared, as well as whether the number of materials published in this area has varied much over a 10-year span of study. Behavioral bibliometric analysis was also undertaken on a sample of the population, analyzing the citations within the sample in order to identify principal works and authors cited within Nietzschean literature. A brief biography is included, as well as an overview of Nietzsche's philosophy. Data are presented in one figure and eight tables. Suggestions for future research are included. Three appendices contain sample "Philosopher's Index" records; sample discards from "Philosopher's Index" initial data set; and sample "Arts and Humanities Search" records. Contains 37 references.
