Electronic but not free -- Marshall and Putnam counties, Illinois

At Wholly Genes Archive CD Books USA offers for $14.95 a download of the unindexed but now every-word-searchable book:

Don't bother with my summary when you can read one from Barbara Vines Little, CG.

The latest Wholly Genes newsletter includes notices of new downloadable books (PDF) for sale, including two that treat places other than New England or the mid-Atlantic:

Jacob Piatt Dunn's 1919 Indiana and Indianans: A History of Aboriginal and Territorial Indiana and the Century of Statehood. Barbara Vines Little, CG, observes, "Researchers stopping to read a particular entry are likely to find themselves completing the chapter before moving on to the next item of interest." I observe that this every-word-searchable version is noticeably less expensive than you can get the hard copy at abebooks.com.

Rev. A. B. Cristy's 1896 Cleveland Congregationalists 1895: Historical Sketches of our Twenty-Five Churches and Missions. Again, I can't find this for even twice the price as a used physical book.

(Although I am a satisfied user of Wholly Gene's bread-and-butter database product, I have no other connection with them.)
