Nit: please don't user "it's" unless you can substitute "it is" without changing your inteded meaning.

My favorite grammar book, Patricia T. O'Conner's "Woe Is I," is
readable as well as concise and lucid. Here's how she explains it (or
rather "it's" vs. "its"): If the word you want can be replaced by "it
is," you want "it's." If not, use "its." (By the way, her chapter
titles are a hoot; the one on punctuation is called "Comma Sutra.")
