This collection represents numerous donations of original newspapers beginning in 1965 to the Yuma County Historical Society and later to the Arizona Historical Society – Rio Colorado Division. Many of the runs are fragmentary and incomplete. However, a distinguishing feature of the collection is the variety of secondary newspapers, some of which are rare and may be the only issues that exist in any archives or library.
Some of these newspapers have never been microfilmed or scanned. Although some runs have been previously microfilmed, the scattered issues in this collection may fill in existing gaps to the holdings of other library and archives for future re-microfilming or scanning projects.
The microfilm contains only scattered years of a variety of Arizona newspapers. They may have been donated by researchers working on specific topics.
