Dick sold his first story in 1952. From that point on he wrote full-time, selling his first novel in 1955. The 1950s were a difficult and impoverished time for Dick. He once said, "We couldn't even pay the late fees on a library book." He published almost exclusively within the science fiction genre, but dreamed of a career in the mainstream of American literature. During the 1950s he produced a series of nongenre, non-science fiction novels. In 1960 he wrote that he was willing to "take twenty to thirty years to succeed as a literary writer." The dream of mainstream success formally died in January 1963 when the Scott Meredith Literary Agency returned all of his unsold mainstream novels. Only one of these works, Confessions of a Crap Artist, was published during Dick’s lifetime.[13]

In 1963, Dick won the Hugo Award for The Man in the High Castle. Although he was hailed as a genius in the science fiction world, the mainstream literary world was unappreciative, and he could publish books only through low-paying science fiction publishers such as Ace. Even in his later years, he continued to have financial troubles. In the introduction to the 1980 short story collection The Golden Man, Dick wrote: "Several years ago, when I was ill, Heinlein offered his help, anything he could do, and we had never met; he would phone me to cheer me up and see how I was doing. He wanted to buy me an electric typewriter, God bless him—one of the few true gentlemen in this world. I don't agree with any ideas he puts forth in his writing, but that is neither here nor there. One time when I owed the IRS a lot of money and couldn't raise it, Heinlein loaned the money to me. I think a great deal of him and his wife; I dedicated a book to them in appreciation. Robert Heinlein is a fine-looking man, very impressive and very military in stance; you can tell he has a military background, even to the haircut. He knows I'm a flipped-out freak and still he helped me and my wife when we were in trouble. That is the best in humanity, there; that is who and what I love."
The last novel published during Dick's life was The Transmigration of Timothy Archer. In 1972, Dick donated his manuscripts and papers to the Special Collections Library at California State University, Fullerton where they are archived in the Philip K. Dick Science Fiction Collection in the Pollak Library. It was in Fullerton that Philip K. Dick befriended budding science-fiction writers K. W. Jeter, James Blaylock, and Tim Powers.
