Illinois and Indiana county histories on line at BYU

Since some folks think I'm draining their purses by mentioning books that have to be purchased, I'll continue my BYU county history series with a list of those on line from Illinois and Indiana:

ILLINOIS: Champaign, Coles, Fulton, Jo Daviess, Knox, Lake, La Salle (3), Lake, Macon, Marion, McDonough, McLean, Morgan, Will

INDIANA: Adams, Allen, Bartholomew, Clark, Clay, Clinton, Delaware, Elkhart, Gibson, Grant, Henry, Jay, Kosciusko, LaPorte, Miami, Putnam, Randolph, St. Joseph (2), Shelby (2), Steuben, Tippecanoe, Vanderburgh, Wabash (2), Wayne (2)

Unfortunately, it's not a simple matter to reach their advanced search interface. A direct link doesn't work, so here's my route: first go to the Harold B. Lee Library Online Collections. Even though you want ultimately to search all collections, select the left-hand tab for "Multimedia and Images" in order to get a search box. Don't type anything into the search box, just hit "go." In the resulting window, ignore any actual results. Instead, click on "advanced search" in the newly apparent menu at the top. Then, in the advanced search window, type in "Michigan county" or whatever you want to search for in more sophisticated ways.
