I think it's time for some updating, hence the question. If you have a favorite, I'd like to know. I've been trying to find a good grammar book and there's so many to choose from. Perhaps it doesn't matter as long as I have one. But if you have one you swear by, post it below please.
I wish I had something to offer in return, but I don't. Instead, this is just me asking for help from all you wonderful writers. :)
