I don't find the anti-semitism charge very credible, he speaks out against anti-semitism very strongly in both the Gulag Archipelago, and several essays. He also claimed that an anti-semitic essay attributed to him was a hatched job by the KGB, which seems at least possible. I also stand by my claim that he was a brilliant writer. I think if you try to take everything in his descriptions of the Gulag system as literal fact, you'll find historical discrepancies, but his work isn't meant to be wholly historic, but rather more expansive.
