The material in the Strom Thurmond Collection Gubernatorial Series includes correspondence (both official and personal), campaign material, speeches and other items documenting Strom Thurmond's term as Governor of South Carolina from 1946-1951. Some of this material was originally part of the holdings of the South Caroliniana Library of The University of South Carolina and the South Carolina Department of Archives and History.

The Pinks series was the cross-reference file for subject correspondence generated by Senator Strom Thurmond's office for the period 1954-1976 before the introduction of the centralized Correspondence Management System by the Senate Computer Center in 1976. The original cross-reference files consisted of pink colored carbon paper copies-hence, the "Pinks" series.
