The Library often receives notes of appreciation from people who have used the digitized images. After the Discovery of Flight Foundation reconstructed an early Wright brothers aircraft, the executive director, Paul Glenshaw, wrote, "To put it simply, it is very hard to overstate the importance of your images in the work of the Wright Experience. … I have regularly pointed your scans out as one of the best uses of digital technology I have ever seen."
Bob Zeller, director of the Center for Civil War Photography, points out in his newsletter that "the Library of Congress has opened its vast storehouse of Civil War negatives to the general public through its Internet Web site, making available thousands of images that were previously difficult or impossible to obtain."
On behalf of his family, a researcher wrote, "My family was thrilled to see the picture of their home and their General Store, both of which have since been demolished. No one in the family had ever seen a picture of their home and seeing the house again brought back so many wonderful memories for everyone. This is just a thank you for all your hard work in compiling, cataloging, caring for and copying these invaluable pictures."
Art historian and Kluge Fellow Margaret Dikovitskaya described the Library as "the" place for the study of images and prints after working with Sergei Prokudin-Gorskii's online color photographs of the Russian Empire just prior to the revolution. She spoke about analyzing Russian Imperial colonial attitudes while her home computer became a time machine through which she traveled as an invisible woman into images that looked real.
