Engineer-in-Training Reference Manual cover The Engineer-in-Training Reference Manual is the most almost useful reference on almost everything I have ever seen. I’ve had a copy since I was a sophomore engineering student, and still refer to it fairly frequently. The professor for my Principles of Engineering class went on about how wonderful this book is and what a great reference it is to keep around for absolutely everything. It usually has something close to what I’m looking for, but not quite close enough to be useful so I end up having to look elsewhere, but it is a good starting point. When it does have helpful information, it is mostly in the mysterious SAE units instead of the normal SI units. Still, it has proved useful in my thesis research (physics/chemistry) on several occasions. I don’t know that I’d buy it if it hadn’t been assigned as a textbook, but it is useful enough that I have kept my copy.
