Back when I first read this book (or at least portions of it), I was an undergrad student at the University of Alberta. The class I was assigned this in was a overview of classical technology. I don't remember the actual course designation anything but it was a very good course and I thoroughly enjoyed it.
At the time I did not know L. Sprague de Camp as anything other than a science-fiction writer. I was soon to find out that he worked alongside other great authors such as Robert A. Heinlein and Isaac Asimov and numerous others who also became famous science-fiction authors.
This book is an overview of the history of engineering from pretty much the very beginning until approximately the 1960s. It was written in 1960 and this therefore limited the author in what he could talk about. In some places I felt Mr. de Camp tended to skip over or at least gloss over some of the pertinent details that led to the invention being discussed but for the most part he gives a very good review of how engineering developed, the people in involved and the historical events that were occurring at that time.
The only major criticism I have of this book (which quite likely may be a minor one for many readers) is that they were nowhere near enough illustrations and other graphical forms of information to allow the reader to understand what is being explained. However, if these were included the book would need to be expanded to multiple volumes.
The book itself is organized by time period, and this does cause some confusion when speaking about certain types of inventions, as there is significant overlap in most of these sciences. I believe it might've been easier to read if the book was to be organized based on the given type of invention and proceeded from the very beginning street to the modern times.
It would be great to see a new edition of this book be published that takes up where Mr. de Camp left off, unfortunately he died in 2000 so it will have to be by someone else.
