This book changed my life

---

Update, stardate May 2011 : Its still a great book, and I know that after I read it my writing became easier to understand and more accurate. Those rocket scientists know a thing or two..

The original link has changed find it here now instead:

NASA SP-7084; Grammar, Punctuation, and Capitalization; A Handbook for Technical Writers and Editors

Original post, stardate December '06:

Well honestly no. But it is worth reading if you write for a living.
Write like a rocket scientist...
