"Don't judge a book by its cover." This is a phrase we've all heard so many times that it's become one of the hard rules of book-lovers. Everyone knows that you aren't supposed to judge a book by its cover, and I mean this only in the most literal way in terms of this discussion. I'm talking about books, not people, for now.
So we've established that it's bad to judge a book by its cover. But why? No one has ever explained to me why book covers shouldn't factor into my purchasing of books. If the cover of a book is supposed to be the book's visual representation, and I think the cover is horrible, than what will I think of the book inside?
If book covers truly didn't matter, then all books would be bound with plain white covers, the only decoration a title, author name, and possibly praise for the book. So, obviously, covers do matter.
My question to you, dear readers, is this: Should we, both bloggers and readers, judge books by their covers? Also, what are some covers that perfectly (or close to perfectly) represent their books' contents?
