This guide offers hints and tips to help you find photographs, as well as general rules for using them. Photographs are intellectual property. Reuse of photographs requires an understanding of copyright, attribution and citation.
Use the Advanced Image Search to specify image sizes (small, medium, or large). Google Image retrieves images based on text in the caption, on the page near the image, and other factors. Images retrieved may be copyright protected.
The digitized images from the Library of Congress includes photographs, fine and popular prints and drawings, posters and architectural and engineering drawings. While international in scope, the collections are particularly rich in materials produced in, or documenting the history of, the United States and the lives, interests and achievements of the American people.
