About a week ago, Tim and I made a quick stop at McKay’s, which, for the record, is the largest, cleanest used bookstore I’ve ever been to in my life. Set high up off Old Hickory Boulevard on Nashville’s west side, McKay’s exterior looks more like a bulk warehouse shopping center than a place that makes it easy for anyone to walk in and buy or sell old books any day of the week. You park your car in an eco-friendly brick parking lot and walk inside to a bright, high-ceilinged space filled with aisles and aisles of books, books on tape, CDs and DVDs. The inventory’s always changing, so even if you’ve just been in a week before, you still never know what you’ll find when you come. In December, I bought a Mexican cookbook that later had me Googling for information about its illustrator, a woman who loved beautiful buildings and architecture as much as I do. Last Monday, we came looking for a children’s book; we left instead with a hardcover Tim had been wanting and a $2 original copy of The Moosewood Cookbook, published in 1977, for me.
