Best CD sleeves out there

I am wondering what everyone's opinion is of the best cd sleeves on the market right now. I volunteer at my local library and I have to replace about 5000 jewel boxes with sleeves to save room...we have run out of space and we need to make the switch asap. I am interested in long time durability, ease of use, and the capacity to stick the liner notes/leaflet in the sleeve with the cd. A deejay told me he uses Tyvek sleeves...any opinions out there?
