There are over 3,400 newspapers that have been published in the Badger State - certainly not all of them are searchable online. But there are quite a few that are indeed available. So go for it - find articles about the events, history, and people that capture the stories of Wisconsin.
Please note that I have not always entered the dates that are included in the collections, as I suspect they will change as more items are digitized. Also I suspect that some of these links may change over time - so if there is a dead link - please use your favorite search engine to find their new location.
