New Access to Old MN Laws
The Office of the Revisor of Statutes has added all the historic Minnesota session laws, from 1849 to 1993, to the Legislature's web site. They are all keyword-searchable.
Since this event happens to coincide with the state's sesquicentennial, Revisor Michele Timmons issued a press release: https://www.revisor.leg.state.mn.us/press.php.
