From presidents to the Civil War, many of the historical photos you have seen in the Times News came from the Library of Congress website, LOC.gov, a great source of information about this nation’s history and government. If you are doing research, the library has collections of documents dating back to the nation’s beginning that can be viewed online and downloaded as PDF files. If you are a teacher trying to create visual aids for a class project, you can download photographs and artwork that cover everything from presidents to everyday people, places and events.
