Hello i will buy the
ACI 318-08 Building Code Requirements for Structural Concrete and Commentary
but when i checked amazon, i saw a 2009 version. on NCEES reference books list given at the last page of construction depth exam specs, they show 2008 version. first of all if there is a 2009 version why do they show 2008 version?
also 2009 versin on amazon seems to be cheaper than 2008 versin. why might that be? what am i missing here?
bottom line, what should i buy?
