Hello,

I am thinking of building a bookcase. I am wanting it to be done
rather nicely(ie. dovetailed tops, wooden standards, sliding
dovetails, ect.). However, I do not know what to do for the
backing ,and I do not want plywood backing on it. Any suggestions?

Plywood. You won't see it once the bookcase is loaded.

Don't sweat over "crap" grade secondary wood. Some of the finest
antiques had absolute crap backs and drawer bottoms.
