In discussing the work of indexing the Harvard Theological Review, I shall begin by describing the organization and development of the project, and the various ideals and principles involved in its design. Then I shall show what some specific keyword selections will call up on searches; these selections collectively exemplify the many diverse and distinctive features of the Harvard Theological Review's collection. This article merely serves as an introduction to the Index; when I complete the project, I shall elaborate further on various matters and exemplary elements in a forthcoming expanded version of this lecture-based article.
