Engineering Manual: A Practical Reference

It's a pity this is out of print. I have the 2nd edition which was one of the first general engineering books I ever bought. I still use it regularly. Starting with math and working through all engineering fields (up to nuclear engineering), it's well organized and clearly written. Not an academic book, this is targeted at working engineers who need quick access to reliable data or who need to call upon a skill which has become rusty with lack of use. Highly recommended if you can find it!

One of the best general engineering reference manuals ever written.

The book holds the most important equations that an engineer will need in the working feild. This book is a handy size that allows one to bring along with them unlike the full lenght Perry's chemical engineering handbook. It is a must buy for a working engineer
