Recommend a good online Rock Island history site

Looking for a good online source to read about the Rock Island and the story leading up to their bankruptcy and abandonment........or perhaps a good book on the same subject.

Here's a link to the Rock Island Technical Society, check the "History" link on the right side of the page...

If you have access to back copies of Trains check out anything by Dr. Ed Brunner; this gentleman worked as a block operator for the Rock in the years when he was firming up his education, and one article in particular, in the June, 2004 issue, contains a blow-by-blow description of exactly how conditions on the Rock's main lines deteriorated during the 1970's.

If you can locate a copy, almost the entire March 1983 issue of Trains magazine was devoted to the history and demise of the Rock Island.
