I have been reading a lot on this subject lately (because I am doing a program on it) so I feel like I have become something of an expert. This is the oldest book I read on sanitation history and perhaps the dullest. The text itself has some interesting facts and there are great pictures throughout the book. However, the author has a very abrupt way of writing and seems to jump around a lot. It is also all black and white which means there is nothing that stands out on the page. I am sure this is because of the age of the book, but it does pale in comparison to the others I have read.
