I remember this well. My recollection is that they were declared genuine by "experts" who had a financial interest in the diaries being accepted as genuine. Very shortly after they were scrutinized by true experts, they were proven to be forgeries. I also remember an article in Time magazine about it. In the articles the true experts mentioned how stunned they were at the ease in which the diaries were proven to be fake. The binding or the ink or something like that was found to contain a type of plastic that had not even been invented in 1945. Handwriting analysis also showed many discrepancies, but the chemical analysis was conclusive. This was not a case of some experts being fooled. This was a case where the people who committed the fraud tried to deceive the public by presenting co-conspirators as experts. The Bush memos appear to be the same thing.
