snow load per mass state building code 1980's
does anyone have a copy of the massachusetts state building code (msbc) from 80's?  i am trying to find out basic snow load in shrewsbury, ma, specified according to 80's msbc.  the current msbc divides the state into 4 different zones and gives the values for pf in each zone (section 1610.2, figures 1610.1a to 1610.1d).  shrewsbury is in zone 3 with pf of 35psf, but i need to verify whether this was the case in 1988.  your help will be greatly appreciated.
check out our whitepaper library.
dsuh,
i have a copy of the 5th edition of the mass building code that went into effect on 03/24/95. it gives the same value of snow load for zone 3 as the current (6th edition) code.
looks like you need a 4th edition.
i also have an old ansi a-58-1982. it indicates worcester, ma as being squarely in a 40 psf zone.
