Midwestern Newspaper Indices

Joe Beine's Genealogy Roots Blog points to the updated Historical Newspapers and Indexes On The Internet - USA, which has useful listings for Illinois, Indiana, and Wisconsin.

But it's not complete. It refers to the Chicago Tribune 1870-1877 index on Footnote, but if you go directly to the Tribune's own archives you can search 1852-1984. (In both cases you have to pay to see more than a sentence or two.) Also, the Indiana State Library site is supposed to have limited indices for Logansport and New Albany (currently inoperative).
