Here is a trick worth every penny.
Every 2 thousand plus albums of mine are fitted in outer sleeves to protect the covers. The trick is to slide the covers into the outer sleeves OPEN END FIRST. It does two things, allows easy reading of the edge since there is no plastic covering it and it makes it much harder for any dust to penetrate the vinyl since the open end is deep inside the outer sleeve.
I don't know of anyone else doing it. I should have a patent. But you guys get it free of charge right here. Try it, you'll love it.
