Library of Congress

The Library of Congress is located in Washington D.C. Taking up three separate buildings across Capitol Hill, it is the home of the United States Copyright Office and is also the main research institute for the United States Congress.


Most importantly, the Library of Congress is one of the largest resource centers in the world. There are over 150 million items in the Library of Congress catalogue. While going to the Library of Congress in person may not be feasible, there are plenty of online resources and databases provided by the Library for researchers to use. 

Chronicling America

Chronicling America is an online database provided by the Library of Congress. This searchable database provides newspapers from all over the United States from 1777-1963. This database is a great place to find primary sources for NHD projects. 

Student Guide

The Library of Congress also works directly with National History Day to provide resources to students. The Student Guide made by National History Day along with the Library of Congress Teaching with Primary Sources Consortium, provides tips, tricks, and general information for students starting their research process for their NHD project.
