It's difficult to believe that 20 years have passed since Rolling Stone published its first issue. But here is RS editor Wenner's ``impressionistic chronology'' of the period, an anthology of the best the magazine has offered: articles on Charles Manson, Watergate, Karen Silkwood, and the Sex Pistols written by the likes of Hunter S. Thompson and Tom Wolfe; major interviews with Bob Dylan, Mick Jagger, John Lennon; along with 135 photos, by photographers including Annie Leibovitz. A reminder that RS was never just a music magazine, but rather one at the cutting edge of our time. Highly recommended and a bargain. Rosellen Brewer, Monterey Cty. Lib., Seaside, Cal.
