In terms of this anthology in particular, all of Poe's well-known stories seem to be there, including 'The Pit & The Pendulum' and 'The Tell-Tale Heart.' However, Poe's frequent use of foreign languages in his stories can spoil enjoyment, and on at least two occasions I could not fully grasp the ending of a story because no translation to these languages was given in this edition. This is a particular concern for the opening story, 'Duc de L'Omelette'.
In terms of Poe's writing, my opinion is divided. His stories (those in this book, at least), seem to be either his famous tales of terror or more essay-type pieces. The tales of terror, especially 'The Pit & the Pendulum' and 'The Cask of Amontillado', are very well-written and I enjoyed them a lot. However, a number of his stories are more like essays and these can be hard to follow in the old-fashioned language Poe used and, if you are unaccustomed to Poe, can leave you waiting forever for the story to begin. Overall, I enjoyed Poe's writings supplied here and they grew on me as I became more used to his style, but they are not as scary nor as easy to follow as more modern tales.
