A Houston housewife who has quietly collected rare Civil War images for 50 years has sold more than 500 early photographs to the Library of Congress.

The library announced the acquisition Sunday and is placing the first 77 images online. On Friday, 87-year-old Robin Stanford delivered the historic stereograph images from her collection to the library.

Some scenes offer a rare glimpse of slave life in the South from images made by Confederate photographers. Most previous photos showed slaves who were recently freed in the North.

Other parts of Stanford's collection show images of South Carolina at the start of the war. Another set depicts President Abraham Lincoln's funeral procession in 1865.

Stanford says the images are like ghosts from the past that reflect part of American history.
