In the article titled Twenty Laws of Complexity(1997), Each Law is presented in a "Brief." Each brief gives the title of the law, its origins, references (if any), statement of the law, and its interpretation. A major part of this document first appeared as an October 1991 presentation package of 24 transparencies which was titled "Generic Design Science: Laws of Generic Design.” These transparencies were used as class material for courses taught by Warfield at DSMC and also before other audiences. I think he handed out the packet to audiences at Ann Arbor, Michigan and at Bell Northern, among other places. Later he updated the presentation package, and the material became "17 Laws of Complexity" which Warfield discussed in his October 1993 "Structural Thinking - Silver Anniversary" paper, and also in his 1995 paper titled "Demands Imposed on Systems Science by Complexity" and it was also printed as "Chapter 9. Briefs of the Laws of Complexity" in the May 1995 monograph "Complexity and Drummers" (and possibly other papers, but I don't know when or which). In 1996 a new version of the manuscript was prepared and printed for distribution as a separate report, with the title "Laws of Complexity." In March of 1997, the document was updated again, with three new laws added, and the title changed to "Twenty Laws of Complexity" On 29 April 1997 "Twenty Laws of Complexity: Studies in the Abuse of Reason" was submitted to Systems Research journal edited by Michael Jackson, in Lincoln, England, but was not accepted for publication in the 1997 version. Subsequent rewriting by Warfield to comply with requests of reviewers and editors resulted in a 1999 journal article "Twenty Laws of Complexity: Science Applicable in Organizations" which differs so much from the 1997 version that it is cataloged as a completely separate document.
