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.
