After learning about this book fro a fellow Goodreads Architecture fan (Thanks Holly!), I picked up a copy and it quickly became a favorite of mine. In simple and explanatory language, it explains the history and distinguishing features of architectural styles (Colonial, Gothic, Victorian, etc). Different than most books of this ilk which use photographs of their examples, it does this mostly with a huge amount of line drawings of the buildings, which makes it much easier to pick out the small details that distinguish one style from another (or a later "Revival"). Also it covers church and Civic/Commercial buildings, which aren't often covered in the same book. A must have for any house-watchers, Architecture enthusiasts, and people who want to learn the language of architecture that exists all around them.
