Thanks for helping, @gglendon, and @jerrytomb. It seems that the thing I want is a bit elusive. I want to have the disc, the booklet and the tray card all to fit in one sleeve - plus have a 1" (or so) tab running across the top that has a pocket for a label to be inserted. This allows it to be stored in a file cabinet-like device, and flipped through quickly. I don't think the Case Logic, or the Vinyl Storage folks have all the features I'm looking for (though that Vinyl Storage place may have solved other things for my record collection!).
I ordered the DiscSox in smallest quantity to see if they work - they look as if they might.
Grateful to all,
David
