Dear Barbara,
  You may know this already, but in case you do not, The Compendium has been
reprinted recently and almost all dealers who handle books will be able to
sell you one. The content has not changed from the 3rd printing, and some
things need to be changed, but it is still a very good reference.
    Good hunting,

Virginia Beach, Va. right now.
