BookLamp's StoryDNA Viewer is a corpus search tool designed to find all books sharing a user-selected set of characteristics ('StoryDNA'). From the resultant list, users can then view a book's entry in BookLamp to get more information about what characteristics it has, in what proportion, and in relation to other books in the database.
