The Library's rare book collections have become more accessible thanks to a project to enter information long hidden in card files and databases into the online catalog.
The Library of Congress owns two copies of the first printing of the Declaration of Independence, also known as the Dunlap Broadside, printed in Philadelphia on the evening of July 4 and the early morning of July 5, 1776. One copy was George Washington's, and the other came to the Library from collector Peter Force.
