This volume would act as a great introduction to PKD for those unfamiliar with his work. All his main themes are represented and the average standard of the stories is very high. I'd read most of them before in one place or another but none of it was time wasted for me.

The Tempunauts: The Russians prove themselves better educated - they call them Chrononauts.

The Electric Ant: Is there such a thing as objective reality? Pure, distilled PKD.

We Can Remember it for You Wholesale: The inspiration for the much more catchily titled film, Total Recall. The number of films based on PKD stories and novels is pretty big. Stephen King might be top of that tree, though.

Oh, to be a Blobel!: Don't trust your automated therapist? A fun story whatever the take-home message might be.
