Recently, the National Archives released the grand jury transcripts for the trial of Julius and Ethel Rosenberg. This makes news on more than one level since grand jury proceedings are always sealed, but the historical significance of these transcripts was deemed so high that they had to be released. A review of the legal arguments concerning these documents may be found at the Jurist site. A good overview of the Rosenberg case, based primarily on government sources, can be accessed at this CCNY site. A very comprehensive treatment of the trial is here.
