First published in 1955, "Personal Influence" reports the results of a pioneering study conducted in Decatur, Illinois, validating Paul Lazarsfeld's serendipitous discovery that messages from the media may be further mediated by informal "opinion leaders" who intercept, interpret, and diffuse what they see and hear to the personal networks in which they are embedded. This classic volume set the stage for all subsequent studies of the interaction of mass media and interpersonal influence in the making of everyday decisions in public affairs, fashion, movie-going, and consumer behavior. The contextualizing essay in Part One dwells on the surprising relevance of primary groups to the flow of mass communication. Peter Simonson of the University of Pittsburgh has written that "Personal Influence was perhaps the most influential book in mass communication research of the postwar era, and it remains a signal text with historic significance and ongoing reverberations...more than any other single work, it solidified what came to be known as the dominant paradigm in the field, which later researchers were compelled either to cast off or build upon." In his introduction to this fiftieth-anniversary edition, Elihu Katz discusses the theory and methodology that underlie the Decatur study and evaluates the legacy of his coauthor and mentor, Paul F. Lazarsfeld.

In this darkly humorous New York Times–bestselling memoir, the Irish American writer and actor shares charming stories from his first decade in the US. Malachy McCourt left behind a childhood of poverty and painful memories of his father and mother in Limerick, Ireland, when he followed his brother, Frank, to America in 1952. In A Monk Swimming, McCourt recounts the decade that followed. With not much else to his name other than his sharp wit and knack for storytelling, McCourt was unsure what he would do after arriving in New York City. He worked as a longshoreman on the Brooklyn docks, became the first celebrity bartender in a Manhattan saloon, performed on stage with the Irish Players, and told tales to Jack Paar on The Tonight Show. Although McCourt gained success, money, women, and, eventually, children of his own, he still carried memories of the past with him. So, he fled again. He found himself in the Manhattan Detention Complex, otherwise known as the Tombs. He was arrested several times: poolside in Beverly Hills, in Zurich with gold-smugglers, and again in Calcutta with sex workers. McCourt’s journey also took him to Paris, Rome, and even Limerick again, until finally he was forced to grapple with his past. Praise for A Monk Swimming “[A] funny, oddly winning book.” —The New York Times “A rollicking good read that, as the Irish say, would make a dead man laugh.” —The Philadelphia Inquirer “Malachy McCourt, who has habitually regurgitated English in glorious colors to his fellow Irishmen and New Yorkers, here makes his vivid, whimsical, raucous, murderous joy and voice available to the rest of us in tales of riot and glory which build on the story of the McCourts’ early life so dazzlingly told in Angela’s Ashes by his brother Frank.” —Thomas Keneally, author of the international bestseller Schindler’s List
