Chicago, Its History and Builders

So far I haven't found a web site that has digital images of all five volumes of Chicago: Its History and Its Builders, A Century of Marvelous Growth (Chicago: S. J. Clarke, 1912). But if you visit both Google Book Search and Illinois Harvest, between them you can view the whole thing.

A search on the title in quotes at Google Book Search produces three hits. At least on my machine, the top one is volume 5, the second one is volume 4, and the third hit is volume 1. Click on the title page image to make sure what you've got.

Illinois Harvest has four of the five volumes at the following URLs:
Volume 1
Volume 2
Volume 3
Volume 5

Since Volume 4 and 5 have the biographies, this could make a difference.
