Many projects require some research depth into events in the past. Newspapers are good sources for such research as they report on events-of-the-day and often include primary source material.

Deep Web Newspaper Archives Online

US newspaper coverage – ResearchGuides lists links to many newspapers

Library of Congress Newspaper Resource List – LOC does a great job getting the list together of wonderful newspaper archives.

NewspaperArchive.com(commercial) – Known for a large collection. I haven’t used it, so I can’t confirm this.

xooxleanswers.com – Great list of newspaper archives from Xooxle. Good list and a funky name. Two thumbs up.

University of Penn Newspaper Archive – List of US newspaper archives and dates. Looked like a deeper list of Texas newspapers, so this effort may be a deep comprehensive list.
