Some Philip José Farmer recommendations from Dave Langford

OK - Dave is not really calling them recommendations in the obituary in Ansible, #260 (March 2009); but I guess I can take them as such: "He won Hugos as Most Promising New Author in 1953, following his pioneering alien-sex stories 'The Lovers' (1952); for 'Riders of the Purple Wage' in Dangerous Visions (1967); and for To Your Scattered Bodies Go (1971), opening the popular Riverworld series. He was perhaps best loved for the exuberant science-fantasies of his World of Tiers, beginning with The Maker of Universes (1985). The elaborately recursive Wold Newton saga cheekily assumes that a single extended family of mutant supermen includes Tarzan, Doc Savage, Sherlock Homes, Fu Manchu, and so on to Nero Wolfe and James Bond".
