Once or twice a year: I re-read Strunk & White’s Elements of Style (Wikipedia entry) (nerd!).
Big Contrarian → How to Say Nothing in 500 Words. A good read and you’re sure to recognize padding tricks you’ve used.
I have great fondness for books, movies, poems, photos that both show you an example of a thing as well as how to do that thing well.
The Name of the Rose (Umberto Eco), is a great book on top of being an excellent demonstration of how to write a mystery. I didn’t realize that’s what it was until Jeff pointed it out.
