On Writing Well: The Classic Guide to Writing Nonfiction

Not necessarily a technical writing book, but one for writing non fiction: On Writing Well, The Classic Guide to Writing Nonfiction by William Zinsser would be a very good read for everyone who wants to write.

Lately I've been reading about the functional artist and writer because ultimately they do similar work to what we do.

On Writing Well is also good.
