THE SIXTIES: The decade remembered now, by the people who lived it then, edited by Lynda Rosen Obst; designed by Robert Kingsbury (Random House/Rolling Stone, $19.95; paperback, $9.95). Rolling Stone magazine, currently celebrating its tenth year, was not around when most events of the '60s happened, but in retrospect it seems the decade's predestined poet laureate and official chronicler. Assembled under Rolling Stone's auspices and partly from its pages, this panoramic survey of the period recaptures its most significant events and revives some of its flavors - and if the coverage is more broad than deep, if much of the period is treated as a sort of media event, that seems a part of the '60s scene, too. Name it and, if it is of interest to the Rolling Stone readership, it is likely to be somewhere in these artfully haphazard pages: Tom Wolfe on the surfing craze, Gloria Steinem on the women's movement and James Meredith on his enrollment at Ole Miss; acid and Woodstock; Janis Joplin, the Beatles and Bob Dylan; Hell's Angles; the assassinations of Medgar Evers, Malcolm X, Martin Luther King, John and Robert Kennedy; Woodstock and Altamont; Hell's Angels, the Yippies and the Chicago conspiracy trial; My Lai and Manson. The prose is pared to the bone to fit it all in, even in the book's large format, but some of the pictures are blown up to poster size with double gatefolds.
