Primary Source Sets
The Minnesota Digital Library (MDL) Primary Source Sets are designed to help students develop critical thinking skills by exploring a variety of topics related to Minnesota’s history and culture. Using both primary and secondary sources, these sets bring together resources in new ways to help students better understand historic events in their context.
Drawing materials from libraries, archives, and museums across Minnesota, these sets use letters, photographs, advertisements, oral histories, postcards, newsletters, speeches, and more. Each set includes a topic overview, ten to twenty primary sources from the MDL collection, links to related resources, and a section called “Think Like a Historian” which offers discussion questions and classroom activities. We invite educators and researchers to use these primary source sets in their teaching and learning.
