In his long writing career (1950 – 1982) Philip K. Dick wrote over 40 novels and 100 short stories. A good place to start finding more information is Dave Hyde’s (Lord Running Clam) 'pkdweb'.
To buy Philip K. Dick books the best places are your local bookstores but if you must go online then Lord Running Clam would NOT recommend online retailers like Amazon but specialist bookstores like http://www.thephildickian.com or Mark Ziesing Books: http://www.ziesing-books.com.
Many fans like to see the cover art of the different editions of PKD books from around the world. The best place to see this cover art is at Henri Wintz's excellent website devoted to PKD cover art: http://pkdickbooks.com.
