I am building a bookshelf and where the pieces meet, (like the runners that will support the shelves for instance), I was going to use wood screws and construction adhesive as well. Or would wood glue be better? I used screws and loctite construction adhesive when I build my subwoofer box, and that thing took so much abuse! In fact, the loctite was what I used to secure the air tube and the only thing that kept it in place. Held up like a champ. So, adhesive? woodglue? Does it really matter?
