May I Quote You on That?: A Guide to Grammar and Usage - Stephen Spector

Disclaimer: I was sent a copy for no charge from OUP.

Reading this book straight though will no doubt bore people. However, if you or someone you know is attending college, I strongly advise you to buy this book. Spector breaks down the most common errors (using focusing on word choice) and provides history and solutions. The title comes from the use of quotes, and Spector finds some really good ones. He is also engaging.

Good for a student.
