I know that this has been brought-up before but I can't find the older threads. I want to protect my large DVD collection. I currently store my DVD's (keep cases AND snapper cases) upright on an open shelving rack. My room does get quite warm in the summer, but probably no warmer than the inside of a DVD player. The room is clean and as dry as the air is (I do NOT have air conditioning or a dehumidifier). Is this storage solution O.K. or could it be improved? For instance would closed in cabinets be better than my open racks? I have had DVD's for over 3 years and have not noticed any deteoriate (touch wood!). Suggestions however, would be appreciated.
