It was about a year ago that I wrote that the 1882 History of Whitley County (by Goodspeed and Blanchard) was available online through the The Harold B. Lee Library Digital Collections.
Now, I've just discovered that Google Books has the 1907 History of Whitley County, Indiana by S. P. Kaler & R. H. Maring online. They say it was digitized a year ago, but I didn't find it until recently.
Both books are searchable online and can also be downloaded.
