I remember the days of Xeroxed fan 'zines with ads in the back for trading "P&B"! First it was tapes of bootleg records, then known generation tapes off a master, next CD's. Now with torrents and sites like Dime it's so easy to have a giant collection. I think torrents DECREASE the value of "for sale" bootlegs since any semi industrious person can get the shows without paying a bootlegger...
