This is an old pre-publication manuscript of “Thinking About Systems” John’s 1987 Editorial in Systems Res. I found the original pre-publication manuscript on an old unmarked floppy, and saved it. I searched for the title on the web, but as far as I can tell this article was not indexed, I  am guessing not indexed because titled as an "Editorial."  However we did get the  1987 publisher’s offprint, nicely printed and formatted with EXACTLY these same words.  The offprint was donated to Fenwick Library special collections with other papers, in October 2000. For a nicely formatted and printed offprint, readers should go to Warfield Collection C00019, Box 29/45, SCRC, George Mason Libraries.  In the GMU Library are copies of author's original manuscript, galley proofs, publisher's offprint, and the Volume General Systems Yearbook XXXI in which the article is reprinted.
