I went out and discovered Philip's works after reading the tagline in the credits for Blade Runner. If I recall correctly that fit into my reading progression just about concurrent with a Vonnegut fixation, and before moving on towards Bova/Zelazney/Varley amongst others on the sci-fi front.

I don't know if I ever found ALL of his works, but there is still a bunch down in the collection of Those Books That I Cannot Ever Dispose Of that rests in the laundry room. Most of the rest of the sci-fi collection is long gone, but those ones - and the Vonnegut's - remain.
