Oh, THANKS!!!
The bookcase is up but I’m missing an anchor pin, and a couple of shelf pegs, but I can go to Lowe’s and see if I can find them. It was a lot easier to assemble than I expected, but it IS an IKEA, so I should have known it would be pretty much a done deal, even by myself.
I will also check to see if I can find a nylon strap about 2.5’ long to anchor the top of it to the wall. It is a perfect fit behind the door!
