I used to have one of these in the dim dark ages of the middle 1980s, but it's losted. Now that we're doing renovations, it would be very handy to have around to size timbers for carports/pergolas. We're also contemplating an upper story extension, and the tables would indicate whether the wall structure we have can withstand the additional load (forget the subfloor for now, that's a total 'nother issue.)

I had a look at the span tables in this forum but they don't tell me too much, and there isn't anything for lower stories. Does anyone know where I can buy one of these books? The one I had was paperback and had a blue cover.

Many thanks

Cecile and Ted (Moondog)
