When I was conducting research for the Library of Congress primary source set "Civil War Photographs: New Technologies and New Uses," I learned way more about photographic technologies that were used before the Civil War than I could fit into the brief teacher's guide.
One of the Library's primary source sets for educators, Civil War Music, has recently been re-tuned to reflect the central role that music played in the Civil War, with the addition of more than a dozen items from the Library's collections.
A photograph of the abolitionist and suffrage activist Sojourner Truth that appears in the Library's newest Primary Source Set for educators, "Civil War Images: Depictions of African Americans in the War Effort," provides an opportunity to discover the questions that the objects in a portrait can raise about the message that image might have been meant to convey.
“Civil War Images: Depictions of African Americans in the War Effort,” explores the myriad ways in which African Americans who participated in the Civil War were portrayed visually.
