Key Ideas is a technique for exploring digital libraries by navigating passages that repeat across multiple books. From these popular passages emerge quotations that authors have copied from book to book because they capture an idea particularly well: Jefferson on liberty; Stanton on women's rights; and Gibson on cyberpunk. We augment Popular Passages by extracting key terms from the surrounding context and computing sets of related key terms. We then create an interaction model where readers fluidly explore the library by viewing popular quotations on a particular key term, and follow links to quotations on related key terms. In this paper we describe our vision and motivation for Key Ideas, present an implementation running over a massive, real-world digital library consisting of over a million scanned books, and describe some of the technical and design challenges. The principal contribution of this paper is the interaction model and prototype system for browsing digital libraries of books using key terms extracted from the aggregate context of popularly quoted passages.
