This isn't a review of the music contained on this 2CD set, which I'm not familiar enough with yet to comment on. It's a review of the package itself, specifically the lack of any sort of essay/sleeve notes or booklet to go with it. I assume this is a new edition, and they've removed the booklet that originally accompanied the package to make the whole thing cheaper, which is fair enough, but maybe it should have been disclosed in the item description.
It's not the end of the world. Put it down as one of the hazards of internet shopping.
