Can you judge a book by its cover? This article points out that a cover "has to visually represent what the book is about since that might be an important cue in identifying a book as belonging to a specific genre." The article includes a reference to "Cat Yampbell at Wayne State University in Detroit ," whose recent report "Judging a Book by Its Cover," gives an explanation. Yampbell says a book cover can be "superficial, ineffective, incorrect and/or misleading."
