Privacy book list

I got a letter in the mail today from Plenum Publishing Corp in NY, advertising a book called _Mind Your Own Business: The Battle for Personal Privacy_ by Gini Graham Scott. It seems I am on a mailing list for privacy freaks. Oh the irony! They must have gotten my name from somewhere. The only two sources that I can think of are the lists for CFP '94 and '95, and a revolver club that I used to be a member of. Has anyone else on the list gotten this ad?
