HeinOnline is a great place to go for historical legal materials.  Hein has recently added to its impressive collection by making available State Statutes: A Historical Archive.  This library has superseded statutes for all 50 states, some going back to 1717.  Utah’s collection goes back to territorial times starting with 1855 and continues until 1951.  Many of these statutory sets contain an index, which can be a great help to researchers attempting to find a particular law.  Search functionality is also available.  This resource will be a great help to those doing historical state legislative research.
