In information handling, a hard copy is a permanent reproduction, or copy, in the form of a physical object, of any media suitable for direct use by a person (in particular paper), of displayed or transmitted data. Examples of hard copy include teleprinter pages, continuous printed tapes, facsimile pages, computer printouts, and radio photo prints.

Magnetic tapes, diskettes, and non printed punched paper tapes are not hard copies.

Dead-tree edition refers to a printed paper version of a written work, as opposed to digital alternatives such as a web page. It is a dysphemism for hard copy. Variations include dead-tree format and dead-tree-ware. "Dead-tree" refers to trees being cut down for raw material for producing paper. Newspapers are, sometimes pejoratively, referred to as the dead-tree-press. The Guardian website on 29 November 2006 wrote:

"Maybe this is more a multimedia victory for Jeff Randall himself: he did manage a dead-tree front page, web scoop, vodcast and major plug on the 10 O'clock news."

Whitney Elizabeth Houston (August 9, 1963 – February 11, 2012) was an American recording artist, actress, producer, and model. In 2009, the Guinness World Records cited her as the most-awarded female act of all-time. Houston was one of the world's best-selling music artists, having sold over 170 million albums, singles and videos worldwide. She released seven studio albums and three movie soundtrack albums, all of which have diamond, multi-platinum, platinum or gold certification. Houston's crossover appeal on the popular music charts, as well as her prominence on MTV, starting with her video for "How Will I Know", influenced several African American female artists to follow in her footsteps.

Houston is the only artist to chart seven consecutive No. 1 Billboard Hot 100 hits. She is the second artist behind Elton John and the only female artist to have two number-one Billboard 200 Album awards (formerly "Top Pop Album") on the Billboard magazine year-end charts. Houston's 1985 debut album Whitney Houston became the best-selling debut album by a female act at the time of its release. The album was named Rolling Stone's best album of 1986, and was ranked at number 254 on Rolling Stone's list of the 500 Greatest Albums of All Time. Her second studio album Whitney (1987) became the first album by a female artist to debut at number one on the Billboard 200 albums chart.

Steven Adler (born Michael Coletti; January 22, 1965) is an American musician. He is best known as the former drummer and co-songwriter of the hard rock band Guns N' Roses, with whom he achieved worldwide success in the late 1980s. Adler was fired from Guns N' Roses over his heroin addiction in 1990, following which he reformed his old band Road Crew and briefly joined BulletBoys, which both proved unsuccessful. During the 2000s, Adler was the drummer and frontman of the band Adler's Appetite, and since 2012, he has held the same positions in the band Adler. He appeared on the second and fifth seasons of the reality TV show Celebrity Rehab with Dr. Drew, as well as on the first season of its spin-off Sober House.

Adler was born Michael Coletti in Cleveland, Ohio, the son of an Italian-American father and a Jewish American mother. His father soon left, after which his mother, Deanna, moved the family to Los Angeles, California. He was renamed Steven in observance of Jewish traditions, and he took on the surname Adler from his mother's marriage to Melvin Adler. He has an older brother, Kenny, and a younger half-brother, Jamie. Adler grew up in the San Fernando Valley until the age of 13, when he was sent to live with his grandparents in Hollywood due to his bad behavior. At Bancroft Junior High, Adler befriended Saul Hudson, later known as Slash; they met when Adler had a skateboarding accident and Slash stopped to help him. After ninth grade, Adler returned to his parents' house in the Valley for the remainder of high school, during which he learned to play drums.

Lee Harvey Oswald (October 18, 1939 – November 24, 1963) was, according to four government investigations, the sniper who assassinated John F. Kennedy, the 35th President of the United States, in Dallas, Texas, on November 22, 1963.

A former U.S. Marine who had briefly (October 1959 – June 1962) defected to the Soviet Union, Oswald was initially arrested for the murder of police officer J. D. Tippit, on a Dallas street approximately 40 minutes after Kennedy was shot. Suspected in the assassination of Kennedy as well, Oswald denied involvement in either of the killings. Two days later, while being transferred from police headquarters to the county jail, Oswald was shot and killed by nightclub owner Jack Ruby in full view of television cameras broadcasting live.

In 1964, the Warren Commission concluded that Oswald acted alone in assassinating Kennedy, firing three shots, a conclusion also reached by prior investigations carried out by the FBI and Dallas Police Department. In 1979, the House Select Committee on Assassinations concluded that Oswald fired the shots which killed Kennedy, but differed from previous investigations in concluding he 'probably' did not act alone. The evidence used to form this conclusion has since been disputed.

The Zodiac Killer was a serial killer who operated in Northern California in the late 1960s and early 1970s. The killer's identity remains unknown. The Zodiac murdered victims in Benicia, Vallejo, Lake Berryessa and San Francisco between December 1968 and October 1969. Four men and three women between the ages of 16 and 29 were targeted. The killer originated the name "Zodiac" in a series of taunting letters sent to the local Bay Area press. These letters included four cryptograms (or ciphers). Of the four cryptograms sent, only one has been definitively solved.

Numerous suspects have been named by law enforcement and amateur investigators, but no conclusive evidence has surfaced. In April 2004, the San Francisco Police Department marked the case "inactive," yet re-opened the case at some point prior to March 2007.^{[dead link]} The case also remains open in the city of Vallejo, as well as in Napa County and Solano County. The California Department of Justice has maintained an open case file on the Zodiac murders since 1969.
