I choose the articles Alton encyclopedia 1880 and STL encyclopedia 1879 buy reading the Alton article I can assume that it is going over the history of the areas and important information on the region and its overall land mass. I think that STL has more Roads and history due to it being a popular area due to it being a larger area.
After reviewing the article on Voyant tools I was wrong, the article on Alton spoke more on the history and the land mass than the still one. Words such as River and Miles were mention on the page 3 different times. where the article on STL mainly focused on western history and what they used to produce in the area and the effect that slaves had on the area.
