I spend an inordinate amount of time in bookstores. While I like a Borders or Barnes and Noble just fine, the real treasures are in the small shops; independent sellers, specialty shops and used book stores. Front Royal is blessed with the presence of Royal Oak Bookshop, my own favorite reef on the ocean of bibliomania. You can take a virtual tour on their website. I would recommend a visit in the flesh if you are in the area.
Royal Oak is a small store with a constantly changing stock of new and used volumes. Literally anything may come through, like shells washed up with the tide. One day there may be nothing of interest. Come back later, and there is that odd little book you have searched for all your life. Some years back, I found on their shelves a copy of In The Service Of The King, the memoirs of my great-grandfather, the Reverend Joseph Dunn, concerning his life as an Episcopal priest in Virginia in the early part of the last century. Up until that moment I had good reason to believe the only copies in existence were in the hands of family or moldering in the State Library in Richmond. The chain stores may offer discounts, but they can't give you miracles.
