Solar Lottery 1955 (these years are the publication dates.There are earlier known dates of authorship for some of them) - This is an A.E. Van Vogt pastiche. It’s fun but immature.

The World Jones Made 1956 - Has good ideas and I enjoyed reading it, but it’s pretty messy and should have spent longer in the oven.

The Man Who Japed 1956 - This is a satire about a guy who cuts the head off of a statue of the founder of his collectivist distopia while in a fuge state (or something like that). It’s significantly better an more polished than the two books that came before it.

The Cosmic Puppets 1957 - I haven’t read this, but the guys on the Dickheads podcast all hate it.

Eye in the Sky 1957 - A bunch of people fall into a particle accelerator and start shifting between alternate realities created by the minds of the people involved in the accident. It has some flaws, but it’s really good, probably my favorite of this era. The first one that really feels like what you expect from a PKD novel.

Time Out of Joint 1959 - “A novel of menace,” they tried to market this as mainstream fiction instead of science fiction. But it’s sci-fi and is a fairly representative PKD “normal guy starts to experience shifting reality” story.

Vulcan’s Hammer 1960 - I haven’t read this yet but I own it, maybe I’ll read it soon. Most people, including PKD, don’t like it much, but I’ve heard people stick up for it. It’s supposed to be really pulpy.

Dr. Futurity 1960 - I think this is supposed to be another corny pulp novel, but I haven’t read it either.
