The South Central Regional Library was first established in 1965 as the Morden-Winkler Regional Library, as a result of referendums in both towns. Library branches were officially opened in the two locations on October 20, 1965.
In 1976 the Rural Municipality of Stanley joined the system as a third partner and the library’s name was changed to the South Central Regional Library. A library branch was opened in Altona when the town became a partner in 1988. The Town of Gretna became the fifth partner of the library region in 1992. The Rural Municipality of Rhineland and the town of Plum Coulee became partners in 2001 and 2002. The Rural Municipality of Thompson joined in 2009.
