What storage conditions are best? Most of my cds and dvds are in slimline jewel cases and boxed in filing boxes or shelves in cool, dry dimly lit area. I don't write on them prefering to print content list on a slip sheet slipped into the locks on the cover of the jewel case so there is no contact with the disc itself. When I burn them I always authenticate the burn for integrity comparing it to the original document/file. What else should I do...beside checking them every year (which, considering the HUNDREDS of cds I have already archived would be a daunting endeavor!)?
