Ebook: The American Heritage Guide to Contemporary Usage and Style

As a professional writer, I'm fairly knowledgeable about everyday usage issues. I rely on a good reference to help me with more arcane usage topics. I've needed to consult this volume about 15 times since I bought it, and it has not discussed a single one of my questions. No exaggeration -- not one! Sadly, the book I used to work with is now out of print.

I'm about to toss the American Heritage because I wouldn't even want to donate it to my local library.
