Bestsellers database

University of Illinois professor John Unsworth's 2006 graduate seminar on “Twentieth-Century American Bestsellers”generated a browsable database of bestsellers - a truly useful and fascinating class project.  Unsworth was apparently training his students to think about books from every conceivable angle; each of the 337 entries includes an amazing wealth of detail about the book's author, history, appearance, reception, sales, translation, serialization, pagination, etc.
