Judging a book by its cover

I have always heard the saying: Don't choose a book by its cover, however I always end up doing it, at least to some degree.  This is why I believe in the importance on having a strong book cover design.  The cover should complement the book itself.  It should speak to the reader, and give an idea of what he will find inside.  It should be creative, attractive, witty.  Chip Kidd mentions in his Ted talk : http://www.ted.com/talks/lang/en/chip_kidd_designing_books_is_no_laughing_matter_ok_it_is.html

many examples and how he came up and the reasons behind coming up with his book covers.  I found the talk both funny and inspiring.  

Keeping Chip Kidd's principles of book cover design in mind,  I took a look at the following book covers from this website: http://bookcoverarchive.com/

These are the three book covers I chose to analyze: 

                                

The first one attracted me because of the graphic design element.   It resembles motion and there is certain depth to it.

The second one attracted my attention with its use of colors.  Bright, lively colors do remind me of India and for me it is an inviting cover.

The third one looks interesting because of the clock and more specifically because the time it is portraying.  The time is tenen to three, and the title is Wide Awake so it really makes me go back to those times where insomnia does happen.  What is it that you do at ten to three, when you can't manage to fall to sleep?  

In the end, my conclusion is that cover pages are an essential element to a book.  Even though one must not judge a book by its cover, it is undoubtedly the first element one sees.  If you do not know anything about the book, such as the author or heard nothing about the title, then the cover will attract or detract you from looking into the book further.  I love art, and the book cover has the potential of being the book's representation in a few images, fonts, colors and design.
