The Wisconsin Statutes as hosted by LawServer come from the Wisconsin legislature, and are updated after the legislature updates its own version of the Statutes. The legislature does not immediately update the Statutes when a new law is enacted, however. So to bring your research up to the date it is sometimes necessary to look for laws enacted since the latest version of the Statutes was published. That information is available here.
