I've known the publisher for many years. I'll go remind him of this information and see what I can get stirred up :-)
Oh, good! :) If you do talk to them, please encourage them to consider reissuing the book in an updated edition. I've found it to be an invaluable research tool, and there's so much that could be added since it was published, especially by crossreferencing it with things that have been released since then like the Venona files, KGB files, the transcripts of McCarthy's Senate hearings, biographies of various Hollywood and political figures incorporating information from FOIA files, etc.; plus everything that's been posted here at FR about the Clintons, Gore, and Kerry. A publisher could get a lot of mileage out of all that if they were so inclined.
