But while the famous question, "Are you now or have you ever been a member of the Communist Party?" resonated in the halls of Congress, security officials were posing another question at least as frequently, if more discreetly: "Information has come to the attention of the Civil Service Commission that you are a homosexual. What comment do you care to make?"Historian David K. Johnson here relates the frightening, untold story of how, during the Cold War, homosexuals were considered as dangerous a threat to national security as Communists. Charges that the Roosevelt and Truman administrations were havens for homosexuals proved a potent political weapon, sparking a "Lavender Scare" more vehement and long-lasting than McCarthy's Red Scare. Relying on newly declassified documents, years of research in the records of the National Archives and the FBI, and interviews with former civil servants, Johnson recreates the vibrant gay subculture that flourished in New Deal-era Washington and takes us inside the security interrogation rooms where thousands of Americans were questioned about their sex lives. The homosexual purges ended promising careers, ruined lives, and pushed many to suicide. But, as Johnson also shows, the purges brought victims together to protest their treatment, helping launch a new civil rights struggle.The Lavender Scare shatters the myth that homosexuality has only recently become a national political issue, changing the way we think about both the McCarthy era and the origins of the gay rights movement. And perhaps just as importantly, this book is a cautionary tale, reminding us of how acts taken by the government in the name of "national security" during the Cold War resulted in the infringement of the civil liberties of thousands of Americans.

    On the Lower East Side, two boys playing at a pier discover a floating human torso wrapped tightly in oilcloth. Blueberry pickers near Harlem stumble upon neatly severed limbs in an overgrown ditch. Clues to a horrifying crime are turning up all over New York, but the police are baffled: There are no witnesses, no motives, no suspects.The grisly finds that began on the afternoon of June 26, 1897, plunged detectives headlong into the era's most baffling murder mystery. Seized upon by battling media moguls Joseph Pulitzer and William Randolph Hearst, the case became a publicity circus. Reenactments of the murder were staged in Times Square, armed reporters lurked in the streets of Hell's Kitchen in pursuit of suspects, and an unlikely trio — a hard-luck cop, a cub reporter, and an eccentric professor — all raced to solve the crime.What emerged was a sensational love triangle and an even more sensational trial: an unprecedented capital case hinging on circumstantial evidence around a victim whom the police couldn't identify with certainty, and who the defense claimed wasn't even dead. The Murder of the Century is a rollicking tale — a rich evocation of America during the Gilded Age and a colorful re-creation of the tabloid wars that have dominated media to this day.

    A murder. A mystery.The most important person on the scene? The forensic scientist. And yet the intricate details of their work remains a mystery to most of us. Silent Witnesses looks at the history of forensic science over the last two centuries, during which time a combination of remarkable intuition, painstaking observation and leaps in scientific knowledge have developed this fascinating branch of detection. Throwing open the casebook, it introduces us to such luminaries as 'The Wizard of Berkeley' Edward Heinrich, who is credited with having solved over 2000 crimes, and Alphonse Bertillon, the French scientist whose guiding principle 'no two individuals share the same characteristics' became the core of identification. Along the way, it takes us to India and Australia, Columbia and China, Russia, France, Germany, Spain and Italy. And it proves that, in order to solve ever more complicated cases, science must always stay one step ahead of the killer.

    As in the authors' bestselling "Film Art", concepts and events are illustrated with actual frame enlargements, giving students more realistic points of reference than competing books that use publicity stills.

    There are many sources too for basic information on the extensions to the WWW that permit content to be expressed in natural language yet used by software agents to easily find, share and integrate information. Until now individuals engaged in creating ontologies-- formal descriptions of the concepts, terms, and relationships within a given knowledge domain-- have had no sources beyond the technical standards documents.Semantic Web for the Working Ontologist transforms this information into the practical knowledge that programmers and subject domain experts need. Authors Allemang and Hendler begin with solutions to the basic problems, but don't stop there: they demonstrate how to develop your own solutions to problems of increasing complexity and ensure that your skills will keep pace with the continued evolution of the Semantic Web.

    Now brought completely up to date, this epic tale charts the rise of four scruffy Liverpool lads from their wild, often comical early days to the astonishing heights of Beatlemania, from the chaos of Apple and the collapse of hippy idealism to the band's acrimonious split.

Witty, insightful, and moving, Shout! is essential reading not just for Beatles fans but for anyone with an interest in pop music.

    Prized as “the best stone in Britain” by Roman invaders who carved jewelry out of it, coal has transformed societies, expanded frontiers, and sparked social movements, and still powers our electric grid. Yet coal’s world-changing power has come at a tremendous price, including centuries of blackening our skies and lungs—and now the dangerous warming of our global climate. Ranging from the “great stinking fogs” of London to the rat-infested coal mines of Pennsylvania, from the impoverished slums of Manchester to the toxic streets of Beijing, Coal is a captivating narrative about an ordinary substance with an extraordinary impact on human civilization.

    But few could have expected that a young Canadian would pen some of the most distinctively American songs, music that seems soaked in the mythology of the Old South. With songs like The Weight, The Night They Drove Old Dixie Down, and Up on Cripple Creek, Robertson and his partners in The Band fashioned a new popular music lexicon that has endured for decades, influencing countless musicians.In this captivating memoir of The Band's storied career, Robertson weaves together his half-Jewish, half-Mohawk upbringing on the Brantford Six Nations Reserve and in Toronto; his odyssey south at sixteen and rollicking early years on the road with rockabilly legend Ronnie Hawkins; the slow formation of The Band, their trial-by-fire with Bob Dylan on his 1966 world tour, and the forging of their unique sound. He recounts being catapulted to fame with the success of their groundbreaking debut, and takes us through the astonishing run of albums that culminated in one of history's most famous farewell concerts: the movie The Last Waltz, directed by Martin Scorcese. This is the story of a time and place--the moment when rock 'n' roll became life, when electric blues legends like Muddy Waters and Otis Rush criss-crossed the circuit of clubs and roadhouses from Texas to Toronto. It's the story of exciting change as the world tumbled into the '60s, and figures like Dylan and The Band redefined music and culture, with a little help from sex and drugs. And it's the moving story of the profound friendship between five young men who together created a new kind of popular music.

    More than just book repositories, libraries can become bulwarks against some of the most crucial challenges of our age: unequal access to education, jobs, and information. In BiblioTech, educator and technology expert John Palfrey argues that anyone seeking to participate in the 21st century needs to understand how to find and use the vast stores of information available online. And libraries, which play a crucial role in making these skills and information available, are at risk. In order to survive our rapidly modernizing world and dwindling government funding, libraries must make the transition to a digital future as soon as possible -- by digitizing print material and ensuring that born-digital material is publicly available online. Not all of these changes will be easy for libraries to implement. But as Palfrey boldly argues, these modifications are vital if we hope to save libraries and, through them, the American democratic ideal.
