I recently acquired a handy little book that is a must-have for Philip K. Dick fans: Philip K. Dick (Pocket Essential Series) by Andrew M. Butler. It's a guide to PKD's fiction that provides short descriptions for all of his major works (that is, the novels and a cherry-picked selection of short stories). It breaks his work down into a few different periods. The one that I've been reading from lately is labelled as "A Double Life 1954-1960". Here's how the books from that period are rated by Butler:
| 1955 | Solar Lottery | 2/5 |
| 1956 | The Man Who Japed | 2/5 |
| 1956 | The World Jones Made | 3/5 |
| 1957 | Eye in the Sky | 4/5 |
| 1959 | Time out of Joint | 5/5 |
| 1960 | Doctor Futurity | 1/5 |
| 1960 | Vulcan's Hammer | 1/5 |
For a pretty comprehensive bibliography of books by and about PKD, check out good old Wikipedia.
