Interesting that all those archives bought acidic sleeves. I wonder what they're using them for. >>> Kurt Nauck <[log in to unmask]> 8/19/2010 12:02 PM >>> When I began manufacture of our line of record sleeves (Disc-O-Files), I considered acid-free card stock. However, the cost would have doubled and I saw no tangible benefit to be gained. In fact, I queried ARSCList and 78-L for opinions on the matter. No one had ever seen a record damaged by an acid-laden sleeve. (Nor have I, and I've probably handled more vintage records than anybody on the planet.) Since introducing the Disc-O-File line, I have sold hundreds of thousands of sleeves to customers including the Belfer Audio Archive, the Library of Congress, the Ward Irish Music Archives, the BBC Broadcast Archive, the National Library of Canada, Harvard University, the International Piano Archives, the National Library of New Zealand, the First Generation Radio Archives, the Georgia Music Hall of Fame, Pennsylvania State University, and the Yale University Music Library. That is not to say that any of these institutions endorse the product, nor am I suggesting that they use the sleeves for any given purpose. Some of these institutions use DOFs to house their primary collections; others used acid-free stock. Some prefer sleeves with flaps and no label holes; others do not. For the most part though, it appears that acidity has not been an issue. In fact, the design of the sleeves coupled with the fact that they come in 11 different sizes has convinced many users to resleeve their entire collection with DOFs.
