In Astounding Days, his autobiographical reminiscence of a youth reading science fiction, Arthur C. Clarke recalled that English fans learned that Woolworth’s was the best place to find the pulp magazines where the stories they wanted to read. “According to legend, all these ‘Yank pulps’ invaded the United Kingdom as ballast in returning cargo ships. Presumably it was worth disposing of unsold issues in this way, rather than recycling the paper.” Colorfully entertaining, Clarke’s recollection also illustrated the incidental—and often unseen and unconsidered—consequences of distribution for publishing’s sales and circulation.
