This small book is densely packed with great information and its only negative is that the book does not cover house styles after 1945. While it is in black and white, several photos are included for each house style and the photos are labeled to highlight the important features. There is so much information, and so many architectural and construction terms used in this book, it is a challenge to even begin to remember it all! To help a pictorial glossary is included. This is a book for anyone interested in old houses. Like bird, mushroom, and tree identification books, it is best owned and kept for reference in your personal library or perhaps kept in your car or backpack where you can easily access it.
