Goggle the Nebraska State Historical Society in Lincoln, Nebraska. They have old newspapers of many counties available on microfilm by interlibrary loan.
I am familiar with the Chappell Register in Deuel County, Nebraska from 1950s. Don't know when it started. There may have been others or it may have gone by other names.
You can contact them at 308/874-2207.
I was born in the next county over & recognize the Bergstrom name but do not have any information about them.
