Guess what trivia freaks, research addicts, editors, writers, diligent students, aimless procrastinators and The Evil Ones have in common? They all find almanacs — yes, almanacs — indispensable to furthering their passions, work and studies — or hastening Death to the Great Satan. The source of this revelation: The Federal Bureau of Investigation, which according to a story in the Washington Post (and other sources), sent out an intelligence bulletin last week warning ” ‘terrorist operatives may rely on almanacs to assist with target selection and pre-operational planning’ because they include detailed information on bridges, tunnels and other U.S. landmarks. Further, the bulletin reportedly asks your local police to be on the alert for suspects carrying almanacs, especially almanacs with notations in them, because such well-used reference works might be a tipoff to something really bad about to happen.
