Second layer of subfloor?

I have an older home with 1x6 solid plank subfloor running diagonally. I have already hammered down all the existing nails and placed screws in every board along the joist. But there are variations in the thickness of the boards and the floor still seems very hollow.

I would like to put a layer of 3/4 T&G plywood over the existing subfloor to stiffen it up and level out the uneven boards. My question is do I glue this second layer down to the first, or should I place roofing paper between the two before I screw it to the joist.

I plan on installing 5/8" or 3/4" strip wood flooring.

Thank you for any help.

Glue and screw to prevent squeeks. Are you sure you need another layer of subfloor? If you use 3/4 inch hardwood it will stiffen up the floor pretty well.
