What's the best grammar reference book or website?

If you want one that reads like a story, you might consider getting “On Writing” by Stephen King. It’s a good book and a great resource. I’ve also used a couple others but they were too dry to get any information out of .

You can get a little more information on the book here: http://en.wikipedia.org/wiki/On_Writing

I also use lifehack occasionally so you might try looking through the following for some quick examples: http://www.lifehack.org/articles/lifehack/guide-to-grammar-and-writing.html

I use the “Chicago Manual of Style” – an exhaustive reference. There’s also Strunk & White’s “Elements of Style” and Robin Williams’ “The Mac is not a Typewriter” if you’re looking for a smaller, paperback source.

My mom gave me the strunk and white book for graduation. i was not impressed. instead I usually use the Chicago Manual of Style Online. I would definitely characterize it as definitive. (heehee)

You should check out Grammar Girl’s blog and podcast. She handles mostly little grammar issues that are nagging or that pop up on a normal everyday basis. Here’s the link

The Purdue online writing labs are an excellent resource for English writing in general and grammar too! Link is here: http://owl.english.purdue.edu/

Merriam-Webster’s Concise Dictionary of English Usage. Instead of laying down intimidating right and wrong rules, it presents the evidence, and lets you make up your own mind.

I’ll cast my vote for the “Chicago Manual” as well.
