It is located in the Greater Chambersburg area and serves readers in Franklin, Cumberland and Fulton counties in the Commonwealth of Pennsylvania.

The newspaper also publishes a weekly total market coverage product, The Advertiser, and a monthly Faith magazine.

Since 1869, when the first edition came off a flatbed press in a Main Street building in downtown Chambersburg, Public Opinion has been a part of life in the Cumberland Valley, and the county's most comprehensive source of local news and information.

It was later used as a canteen for World War I soldiers passing through town and had a variety of manufacturing uses before 1956, when Public Opinion assumed occupancy.

In 2007, Public Opinion replaced its fifty-year-old letterpress with a Goss Urbanite offset press, and also introduced a Sunday edition.
