Book Cover Designs US, UK, Movie

October is National Book Month. Though we are taught never to judge a book by its cover, as a graphic designer I can appreciate great book cover designs.
It wasn't until I began purchasing books online that I realized how one book can have multiple designs. US books and UK books can have different designs for one book, for varying different reasons, book to movie designs; once a book hits the theatres, a cover design may change for a short time to encourage individuals to purchase the book, also special edition books can get revised look. Let's not forget books that have been reprinted. Those books can have several different covers to fit the time and or audience. 


On the next tab I found a few books that have different designs based on the country, Books that have been reprinted and books that have become books and have a cover change.
