Through the digitization of text corpora, information previously unavailable has become increasingly common. Among this information, the table of contents and index have been under-utilized for book search. This information can be represented visually, making it easier for the user to analyze the data efficiently and intuitively.
By gradually narrowing in focus, from a large repository, to a few books, to finally the underlying content, the user can quickly find information relevant to their interests. We present a multi-tiered visualization system which incorporates this information, with the goal of guiding the user more effectively towards information that is directly related to their interests.
