This book can be read very quickly as an overview of Delaware's history, or the reader can spend much more time delving into the links (e-book) to more detailed descriptions of and about the background for each photo. I found these descriptions to be the most interesting feature of this book. My preference would be to have the details with the photos and illustrations and a bit more of a narrative leading from one topic to another. However, the information is there if a reader wants to access it. The timeline in this book spans from 1900 up to the near present. I found it interesting reading. There were two previous books, covering earlier times in Delaware. I did not read those.
