For links to primary sources available in the UNLV Libraries (these include collections online, in print and on microfilm) as well as to primary source collections freely available on the web see:
Photographs, drawings and other images provide information you can't always get from a text source. Images can provide details of everyday life such as clothing or material culture.
It is important to keep in mind that photographs are not an unbiased reflection of reality -- the photographer chooses what and how to depict a certain scene.
Help: Making Sense of Documentary Photographs, Analyzing Photographs, Analyzing Political Cartoons, Analyzing Material Culture, Making Sense of Films, and Making Sense of Advertisements
Keep in mind that non-UNLV students must be in the UNLV Libraries to use any of the links that include a lock icon.
American Memory from the Library of Congress provides a wide range of primary source materials in all the categories above.
