<P> The ALI and NCCUSL have established a permanent editorial board for the Code . This board has issued a number of official comments and other published papers . Although these commentaries do not have the force of law, courts interpreting the Code often cite them as persuasive authority in determining the effect of one or more provisions . Courts interpreting the Code generally seek to harmonize their interpretations with those of other states that have adopted the same or a similar provision . </P> <P> In one or another of its several revisions, the UCC has been fully enacted with only minimal changes in 49 states, as well as in the District of Columbia, Guam, the Northern Mariana Islands, and the U.S. Virgin Islands . In addition, both Louisiana and Puerto Rico have enacted most provisions of the UCC with only minimal changes, except Articles 2 and 2A, preferring instead to maintain their own civil law tradition for governing the sale and lease of goods . Also, some Native American tribes have adopted portions of the UCC, including the Navajo Nation that adopted Articles 1, 2, 3, and 9 with only minimal changes . </P> <P> Although the substantive content is largely similar, some states have made structural modifications to conform to local customs . For example, Louisiana jurisprudence refers to the major subdivisions of the UCC as "chapters" instead of articles, since the term "articles" is used in that state to refer to provisions of the Louisiana Civil Code . Arkansas has a similar arrangement as the term "article" in that state's law generally refers to a subdivision of the Arkansas Constitution . In California, they are titled "divisions" instead of articles, because in California, articles are a third - or fourth - level subdivision of a code, while divisions or parts are always the first - level subdivision . Also, California does not allow the use of hyphens in section numbers because they are reserved for referring to ranges of sections; therefore, the hyphens used in the official UCC section numbers are dropped in the California implementation . </P> <P> The 1952 Uniform Commercial Code was released after ten years of development, and revisions were made to the Code from 1952 to 1999 . The Uniform Commercial Code deals with the following subjects under consecutively numbered Articles: </P>
