Data communications networking devices
They mostly rate from above average to very good; but nearly all of them are very original studies. Science-fiction can use a bit of grit and sleaze sometimes and most of these are working on those spheres. It has some first-class ideas, like the complete lack of understanding of a corporate lackey of a timeline shift and he goes on with his life in an alternate reality, a dictionary for an alien language, or bartering of stolen dreams. Ratbird and the Alphabet of Amerliorating hope were one notch below the others, but overall it is a solid compilation.
