Here's what I liked: the detailed history of some the of the neighborhoods and the perspective on the development process for the rowhouse as a type. Here's what I found challenging: the use of architecture terms without definition, the repetition, the historical facts without context, the repetitiveness of the analysis. I think they needed a different editor. As a non-architect, I wanted to learn about the different types of row houses I see or have been in. But the architectural jargon was alienating rather than helpful. It felt like the authors had a lot of knowledge they felt compelled to put into the book. While it was organized by time period, I think a more useful means of organizing would have been to take a representative neighborhood and go deeper about the architecture, the social context, etc. Also, the pictures and examples were not uniformly so clearly marked as to help me find the buildings on google earth or something. More and better maps would have been helpful.
I wanted more, but I think the authors were writing for a different audience. I will look for a history of Baltimore generally, and then one for minor hoods I am interested in.
