My Borders has an awful history section. I was able to get 2-3 books on submarines/Uboats. I look on Amazon and there are plenty of books on the subject. Books I would never see at Borders. The books I purchase for a few pennies to 10 bucks. One used book I purchased was signed by the author! I was in Borders Annapolis two weeks ago. Place is huge. Two floors. Not much in history books. Could get CDs' all day though.
