Problem: Background: Stephen Edwin King (born September 21, 1947) is an American author of horror, supernatural fiction, suspense, science fiction, and fantasy. His books have sold more than 350 million copies, many of which have been adapted into feature films, miniseries, television series, and comic books. King has published 54 novels, including seven under the pen name Richard Bachman, and six non-fiction books. He has written around 200 short stories, most of which have been collected in book collections.
Context: In the late 1970s and early 1980s, King published a handful of short novels--Rage (1977), The Long Walk (1979), Roadwork (1981), The Running Man (1982) and Thinner (1984)--under the pseudonym Richard Bachman. The idea behind this was to test whether he could replicate his success again and to allay his fears that his popularity was an accident. An alternate explanation was that publishing standards at the time allowed only a single book a year. He picked up the name from the hard rock band Bachman-Turner Overdrive, of which he is a fan.  Richard Bachman was exposed as King's pseudonym by a persistent Washington, D.C. bookstore clerk, Steve Brown, who noticed similarities between the works and later located publisher's records at the Library of Congress that named King as the author of one of Bachman's novels. This led to a press release heralding Bachman's "death"--supposedly from "cancer of the pseudonym". King dedicated his 1989 book The Dark Half, about a pseudonym turning on a writer, to "the deceased Richard Bachman", and in 1996, when the Stephen King novel Desperation was released, the companion novel The Regulators carried the "Bachman" byline.  In 2006, during a press conference in London, King declared that he had discovered another Bachman novel, titled Blaze. It was published on June 12, 2007. In fact, the original manuscript had been held at King's alma mater, the University of Maine in Orono, for many years and had been covered by numerous King experts. King rewrote the original 1973 manuscript for its publication.  King has used other pseudonyms. The short story "The Fifth Quarter" was published under the pseudonym John Swithen (the name of a character in the novel Carrie), that was published in Cavalier in April 1972. The story was later reprinted in King's collection Nightmares & Dreamscapes in 1993 under his own name. In the introduction to the Bachman novel Blaze, King claims, with tongue-in-cheek, that "Bachman" was the person using the Swithen pseudonym.  The "children's book" Charlie the Choo-Choo: From the World of The Dark Tower was published under the pseudonym Beryl Evans, who was portrayed by actress Allison Davies during a book signing at San Diego Comic-Con, and illustrated by Ned Dameron. It is adapted from a fictional book central to the plot of King's previous novel The Dark Tower III: The Waste Lands and published in 2016.
Question: How many pseudonyms did King use?
Answer: King has used other pseudonyms.
