Query: you need to put print date on book profiles

I am disappointed in these Ed McBain books. You had a special deal so I purchased 4 Ed McBain ebooks. Once I started reading them it was clear they were written long ago. I checked the copyright and it was 1954! These books are 58 years old. I thought they were somewhat contemporary and would have never bought them had I known the copyright date.
