Bricks and Brownstone was the first book I bought when it looked like this house thing was actually going to happen. I was (and continue to be) fascinated by period detail and the different styles of row houses in Brooklyn, and the book provided information overload. I keep going back for reference and I suspect my copy will be heavily dog-eared before we finish work here at the Pink Lady. Sadly, Charles Lockwood, the author of the seminal row house bible passed away today.
While the book was out of print for a while, you can easy get it online (or have the nice people at The Strand order you a copy).
