As I was working the other day building a site, I looked at some competing sites and was a little disheartened because of the many pages of content I found on one in particular. That was until I decided to do a search to find if it was original or not. Ha! I copied an entire sentance from the text, put it in quotes and asked google to search for that "exact" set of words in that exact order.
These words : "The Illinois Central Stone Arch Railroad Bridges are a trio of limestone railroad bridges"
