My sole complaint regards the absence of footnotes. Take "Cask Of Amontillado", for example. It's hardly essential to know that "motley" is the garb of a jester or a clown (or that a "pipe" is a wine cask) in order to enjoy the story, but that information would have been nice to have nonetheless.
In conclusion, this collection is a wonderful bargain, but if you have a little more money you may want to invest in an annotated collection of these tales.
