The title of this collection of Hoffmann stories is misleading: For sure Hoffmann wrote some strange stories (The Golden Pot, Little Zaches Called Cinnabar, The Nutcracker, ...) but those are left out from this volume. There's one of the classical and strange Hoffmann stories that did get included, though: Coppelius, the Sandman. Most of the rest is rather plain stuff, often a bit dull, at times even boring. And most of these other stories are quite certainly not among Hoffmann's major works, with another exception being "Mademoiselle de Scuderi", here entitled "Cardillac, the Jeweller", which works rather well as a classical crime story most of the time, even though the happy ending is a bit strained.
I think this is not the best introduction to Hoffmann's work, but with the Sandman and the Scuderi it at least contains two major works and therefore is not all bad either.
