An interactive interface for visualizing results from a search of a corpus of machine-readable documents, each of which is associated with at least one category of a category hierarchy. The interactive interface includes a page object generation component, a book generation component, a page turning component, a cone tree generation component, and a cone tree rotation component. The page object generation component generates for each document of the results a link page and a content page. The link page of each document includes at least a link to categories of a category cone tree, which visually represents the category hierarchy. The content page of each document includes a portion of the document. The book generation component generates a visual representation of the pages for the documents of the results as a book. The book includes a first area for displaying a first link page of a first document of the results and a second area for displaying a first content page of the first document. The page turning component responds to a cursor control device by causing a second link page of a second document of the results to be displayed in the first area and a second content page of the second document of the results to be displayed in the second area. The cone tree generation component generates and displays the cone tree, which is perceptible as three dimensional and which represents a portion of the category hierarchy. The cone tree represents each category as a node and has a primary display position for displaying first category nodes associated with a first document. The cone tree rotation component responds to the page turning component by causing second category nodes associated with the second document to be displayed in the primary viewing position.
