Yes , thank you I know of the Haggerty and Connoiseurs bags. i am curious if indeed these bags are necessary or is it efficient enough to protect and inhibit the tarnish by simply lining the selves with the silver cloths?

The cloth doesn't exude anything -- it just competes with the silver for the oxygen by providing a bunch of alternative surface. If you leave everything open to the air, then anything not touching silver cloth will just tarnish -- a closet full of air is too much. You don't need the bags per se, but you do need to wrap or enclose in a smaller space like a thin drawer.

Even with the bags you will still need to polish before using I find anyway silver tarnishes even when wrapped in plastic wrap
