Stupid Expensive Textbooks

Ugh, I'm having flashbacks to college.  I can't find my copy of the national building code anywhere, and even though they sell a PDF version of it I can't find it online anywhere to download for free.  Come on assholes, I already dropped about three hundred bucks on the damn thing, you could at least make a free backup copy available when I misplace it.  If I ever legit buy the PDF version someday the first thing I'm doing is putting it up on the Pirate Bay for everyone else in my situation.
