Long acclaimed as the indispensable guide to the political process, Nelson W. Polsby and Aaron Wildavsky's Presidential Elections: Strategies of American Electoral Politics has gone through five editions and sold more than 150,000 copies. So, with Campaign '84 under way, Scribner's has issued a sixth cloth edition of a work New York Times reporter R.W. Apple, Jr. has deemed "essential reading for anyone who wants to grasp what goes on in a presidential campaign" [$15.95], The latest edition examines such subjects as these: why Republicans win presidential elections even though they are a minprity party, why the 1980 election did not cause a major party alignment, and why the effects of political action committees and money are overrated. Of the decades of this century, few have so captivated Americans as the one known as "the Roaring Twenties," and that dazzling, myth-ridden era is recalled anew in Geoffrey Perrett's America in the Twenties, now available as a Touchstone Book [$9.95]. Another recent Touchstone Book is United Nations Ambassador Jeane J. Kirkpatrick's Dictatorships and Double Standards: Rationalism and Reason in Politics, a collection of essays discussing U.S. domestic and foreign politics [$7.95]. With the cloud of a nuclear holocaust looming ever larger in the public imagination, New England has published a new edition of David Bradley's No Place to Hide, 1946—1984, with a foreword by former Presidential Science Advisor Jerome B. Wiesner, who warns, "No one knows how to use nuclear weapons.... There are truly no experts. None!" Bradley's book originally appeared in 1946, was a firsthand account of the relatively "small" atomic tests at Bikini atoll that year, and became one of the works that launched the antinuclear movement [$18.00 cloth, $8.95 paper]. MIT Press is offering a two-volume paperback edition of Marcus Whiffen and Frederick Keeper's American Architecture, with Vol.1 covering the period 1607-1860 and Vol.2 1860—1976 [$10.95 each]. A recent Pantheon paperback is The WPA Guide to Massachusetts, one of the classic commentaries on the states of America prepared by the Federal Writers' Project during the 1930's and including Conrad Aiken's evocation of Deerfield, perhaps the most beautiful passage in any WPA guide [$9.95]. Hastings House has come out with a paperback edition of Parke Rouse, Jr.'s Planters and Pioneers: Life in Colonial Virginia [$12.95]. Rudolph Flesch's controversial Why Johnny Still Can't Read: A New Look at the Scandal of Our Schools has been reissued as a Harper Colophon Book [$4.95]. Two new McGraw-Hill Paperbacks are, respectively, James Pinckney Harrison's The Endless War: Vietnam's Struggle for Independence, acclaimed by History magazine as "the best overall history of the Vietnam War" [$8.95], and Lindsay Anderson's About John Ford, a comprehensive survey of the films made by one of America's greatest directors over a period spanning nearly half a century [$9.95]. Robert Scheer's With Enough Shovels: Reagan, Bush and Nuclear War has been republished in an updated edition by Vintage Books [$4.95],
