On Writing Well by William Zinsser was a great book on writing. Though it's a bit more conceptual than Strunk and White.

I was looking to see if someone had suggested On Writing Well! I agree that it is an excellent resource, especially for those who are already familiar with basic grammar rules and are interested in improving their style.

On Writing Well is entertaining on top of being instructive and informative. Very short read too. Every should get a copy.
