Library of Congress Shares Data Visualizations to Celebrate “Chronicling America” Milestone; More Than 15 Million Digitized Pages From Historical Newspapers Now Available

From the Library of Congress:

This week we celebrate an exciting milestone. Chronicling America, the online searchable database of historic U.S. newspapers, now includes more than 15 million pages! To mark the occasion, we are throwing a #ChronAmParty on Twitter and unveiling a set of interactive data visualizations that help reveal the variety of content available in a corpus of 15 million digitized newspaper pages.

Libraries, historical societies, and other institutions throughout the country have contributed newspapers from their collections to Chronicling America since 2005. This process is part of the National Digital Newspaper Program (NDNP), a collaborative program sponsored by the National Endowment for the Humanities (NEH) and the Library of Congress. The goal of NDNP is to digitize newspapers from all states and U.S. territories. To date, we have more than 2,800  newspapers from 46 states, Puerto Rico, and the District of Columbia.
