I'm just pointing out that my comment was about the list provided by the commenter above and "most" was about that list rather than all of PKD's work. What you refer to as "pedantic", I consider precision and talking about what's being discussed; someone asks "are these his titles", the answer was "yes. most of these are". Nothing more, nothing less.
Back to original list from the parent comment that is the "above" in my comment. X denotes PKD title, O denotes otherwise:
X Time Out of Joint
X The Man in the High Castle
O Martian Time-Slip
X The Three Stigmata of Palmer Eldritch
X Clans of the Alphane Moon
X The Simulacra
X Now Wait for Last Year
O Do Androids Dream of Electric Sheep? (1968)/Blade Runner (1982)
O Ubik
O We Can Build You
X Flow My Tears, The Policeman Said
X A Scanner Darkly
O The Transmigration of Timothy Archer
O Radio Free Albemuth
So..."most" of what exactly?
