The Michigan Newspaper Project is a result of a federally sponsored program that that was designed to catalog all of the newspapers published in the United States, selectively microfilm certain papers, and then to make some of the microfilmed newspapers available digitally.  The work is funded by the National Endowment for the Humanities, coordinated by the  Library of Congress, and within each state organized by a single agency.  In Michigan, the Clarke Library, working with the Library of Michigan, has taken on this responsibility.
