Question: How many books has a winner of multiple Hugo Awards after after winning the John W. Campbell Award born in 1942 written?

The John W. Campbell Award for Best New Writer is an American award given annually to the best new writer whose first professional work of science fiction or fantasy was published within the two previous calendar years.  The prize is named in honor of science fiction editor and writer John W. Campbell, whose science fiction writing and role as editor of "Analog Science Fiction and Fact" made him one of the most influential editors in the early history of science fiction.  The award is sponsored by Dell Magazines, which publishes "Analog".  The nomination and selection process is administered by the World Science Fiction Society (WSFS) represented by the current Worldcon committee, and the award is presented at the Hugo Award ceremony at the Worldcon, although it is not itself a Hugo Award.  All nominees receive a pin, while the winner receives a plaque.  Beginning in 2005, the award has also included a tiara; created at the behest of 2004 winner Jay Lake and 2005 winner Elizabeth Bear, the tiara is passed from each year's winner to the next. <SEP>  She has written more than 60 books since the mid-1970s, including the Hugo Award-winning novels "Downbelow Station" (1981) and "Cyteen" (1988), both set in her Alliance-Union universe. Carolyn Janice Cherry (born September 1, 1942), better known by the pen name C. J. Cherryh, is an American writer of speculative fiction.  She is known for "world building," depicting fictional realms with great realism supported by vast research in history, language, psychology, and archeology.  Her series of fantasy novels set in the Alliance-Union universe, the Morgaine Stories, have sold in excess of 3 million copies. <SEP>  She is one of only five writers who have gone on to win multiple Hugo Awards for fiction after winning the John W. Campbell Award for Best New Writer (the others being C. J. Cherryh, Orson Scott Card, Spider Robinson, and Ted Chiang). Sarah Bear Elizabeth Wishnevsky (born September 22, 1971) is an American author who works primarily in speculative fiction genres, writing under the name Elizabeth Bear.  She won the 2005 John W. Campbell Award for Best New Writer, the 2008 Hugo Award for Best Short Story for "Tideline", and the 2009 Hugo Award for Best Novelette for "Shoggoths in Bloom". <SEP> The Hugo Awards are presented every year by the World Science Fiction Society for the best science fiction or fantasy works and achievements of the previous year.  The award is named after Hugo Gernsback, the founder of the pioneering science fiction magazine "Amazing Stories", and was once officially known as the Science Fiction Achievement Award.  The award has been described as "a fine showcase for speculative fiction" and "the best known literary award for science fiction writing".  The Hugo Award for Best Fan Artist is given each year for artists of works related to science fiction or fantasy which appeared in low- or non-paying publications such as semiprozines or fanzines.  A Hugo Award for professional artists is also given.  The fan award was first presented in 1967 and has been awarded annually.  Beginning in 1996, Retrospective Hugo Awards, or "Retro Hugos", have been available to be awarded for years 50, 75, or 100 years prior in which no awards were given.  To date, Retro Hugo awards have been awarded for 1939, 1941, 1946, 1951, and 1954, although the 1939, 1941, and 1954 Retro Hugos received insufficient nominations for the Fan Artist Hugo to make the ballot.
