Tom Clancy's Net Force Explorers: Cold Case is a young adult novel by Bill McCay that is the fifteenth book in the series Tom Clancy's Net Force Explorers created by Tom Clancy and Steve Pieczenik.
The Shame of the Cities is a book written by American author Lincoln Steffens.
 Published in 1904, it is a collection of articles which Steffens had written for "McClure’s Magazine".
 It reports on the workings of corrupt political machines in several major U.S. cities, along with a few efforts to combat them.
 It is considered one of several early major pieces of muckraking journalism, though Steffens later claimed that this work made him "the first muckraker."
Lincoln Joseph Steffens (April 6, 1866 – August 9, 1936) was a New York reporter who launched a series of articles in "McClure's", called "Tweed Days in St. Louis", that would later be published together in a book titled "The Shame of the Cities".
 He is remembered for investigating corruption in municipal government in American cities and for his early support for the Soviet Union.
Tom Clancy's Ghost Recon 2: Summit Strike is the expansion to "Tom Clancy's Ghost Recon 2".
 There are several minor differences between "Tom Clancy's Ghost Recon 2: Summit Strike", and "Tom Clancy's Ghost Recon 2".
 The most notable being the difficulty, Summit Strike being regarded as the harder of the two.
 Other differences would include new multiplayer modes, such as Heli Hunt.
Thomas Leo "Tom" Clancy Jr. (April 12, 1947 – October 1, 2013) was an American novelist best known for his technically detailed espionage and military-science story lines set during and after the Cold War.
 Seventeen of his novels were bestsellers, and more than 100 million copies of his books are in print.
 His name was also used on movie scripts written by ghost writers, nonfiction books on military subjects, and video games.
 He was a part-owner of the Baltimore Orioles and vice-chairman of their community activities and public affairs committees.
Justin Daniel "Joe" Kaplan (September 5, 1925 in Manhattan, New York City – March 2, 2014 in Cambridge, Massachusetts) was an American writer and editor.
 The general editor of "Bartlett's Familiar Quotations" (16th and 17th eds.)
, he was best known as a biographer, particularly of Samuel Clemens, Lincoln Steffens, and Walt Whitman.
Organized crime in Minneapolis first attracted national attention in 1903, when thug and mayor Doc Ames (1842-1911) was exposed by Lincoln Steffens in the book "The Shame of the Cities".
 Steffens's account and subsequent trials revealed a police department recruited from felons shaking down the Minneapolis underworld on the mayor's behalf.
 Ames later fled the state, spending a short period as a fugitive before being arrested and extradited to Minnesota.
 He was convicted of receiving a bribe and sentenced to six years in prison.
 His sentence was later appealed and overturned.
Tom Clancy's Net Force Explorers or Net Force Explorers is a series of young adult novels created by Tom Clancy and Steve Pieczenik as a spin-off of the military fiction series Tom Clancy's Net Force.
Albert Alonzo "Doc" Ames (January 18, 1842 – November 16, 1911) was a doctor and politician who held four non-consecutive terms as mayor of Minneapolis, Minnesota.
 His fourth term was marked by allegations of widespread corruption which were popularized by muckraking journalist Lincoln Steffens in a 1903 article in McClure's Magazine titled "The Shame of Minneapolis."
 Ames was found guilty of corruption, but after a successful appeal and multiple mistrials the charges were dropped.
Tom Clancy's Rainbow 6: Patriots is a cancelled first-person shooter video game, part of the "Tom Clancy's Rainbow Six" series, announced on the cover of the December 2011 issue of "Game Informer".
 It was to be published by Ubisoft, and was developed by the company's Montreal studio, with additional development by Ubisoft Toronto and Red Storm Entertainment.
 Due to the death of Tom Clancy in October 2013, concern was raised that this game would become the last to bear his name.
 Ubisoft has since stated that they will continue putting Tom Clancy's name on future Tom Clancy titles out of respect for the late author.
