   I have seen a 1971 edition.
   Does anyone know if the 1971 edition is a reprint of the 1969 version?

   Thanks

   I have the 1969 edition and the 1981 edition. I did not know
   there was a 1971 edition. The 1981 is an updated version.
   Not merely a re print.

   I also have the Oct. 1971 edition.  No mention of revision in the
   Preface.  Paul, is there much change or additions in the 1981
   version?  Interesting that there is no copyright printed in the book.

There are quite a few changes. Mostly on the matters of emissions.
