Campbell, Jr., discovered and promoted great new writers such as Isaac Asimov in New York, Robert A. Heinlein in California, and A.E. van Vogt in Canada, whose novel Slan was one of the basic works of the era. Throughout the forties and into the fifties Slan was considered the single most important SF novel, the one great book that everyone had to read. Many SF fans rallied to the cry, "Fans are slans."

Today it remains a monument to pulp SF adventure, filled with constant action and a cornucopia of ideas. And maybe fans really are slans. Read it and see for yourself.
