  :::I think that's how I initially got here - starting this whole thread, see the first two comments at the top.  That's why this section has the name it does, I though I was on an article about the acts.  Anyway, Model Acts come out of all sorts of places (including NCCUSL - sometimes because not enough states like the idea), see this link for more explanation.  That same link gives information on which Uniform Laws have been enacted by which states as does the NCCUSL's web site.  In some cases the answer is only one state or even none.  The page also lists the UCC and implies it is out of the NCCUSL, but it is actually a joint effort between NCCUSL and ALI.  And what do the dates mean?  I don't see the connection between the UCC and the year 2001, I believe there are 2006 versions, though various states have various versions and sometimes different versions for different articles.  I wasn't really meaning to bring up uniform building codes, I notice someone else did in an unsigned comment right above mine though.  I haven't even looked to see if there are relevant pages, some of them rate them though I think, but that's another matter.  I don't really care for pages of lists though. •
