this is a book of his earlier short stories. some of them are pretty good, others just alright. i've never read him before and i suspect he's better to read in a collection of lots of authors - i found reading him all at once to be pretty repetitive. i guess if you are familiar with him and other stories coming out in the 50's and 60's it might be cool to see his progression of ideas, and how he'd keep trying a certain theme to get it right. i guess i was hoping for a little more evolution in the ideas since he was returning to them over and over, but didn't find that. still, i did like some of these, and i enjoyed his paying homage to other sci-fi authors in the stories. i especially enjoyed his personal commentary about the stories themselves.
