Early next week, look for a blog post based on something Grammar Girl said in February on her podcast / blog. In anticipation of that post, let me share this with you: I found out this morning (because I follow her on twitter) that she has a new book out called Grammar Girl's Punctuation 911: Your Guide to Writing it Right (affiliate link) and is available on the Amazon Kindle for 99 cents. For the record, I don't own a kindle, but I read kindle books on my iPod touch and on my PCs.*
It's actually a chapter out of an earlier book of hers, Grammar Girl's Quick and Dirty Tips for Better Writing (Quick & Dirty Tips) (affiliate link). And I'm one to use commas as breathing marks (like we had in our sheet music for Recorder class or Band) and break other punctuation rules, so I figure this is a good place to start, especially if I buy more of her material later on. Writing papers was one of my weaknesses in seminary (and college, and high school, and...) so improving my writing is pretty high on my priority list. If I like this little book, in addition to the stuff already available for free on her website, I may very well jump into other materials she has to offer.
* Yes, I'm aware of the fact that I've probably done something wrong with my punctuation choice. I have a few other books I need to read before knocking out Punctuation 911. But I'll get to it very soon.
