Texas newspapers are among the most popular archived items in the portal and last month the millionth newspaper page was digitized and added to the collection. There are currently 127,604 issues of newspapers in the portal, mostly from small towns. About half the newspapers are publications printed before 1923 -- with some printed as early as the 1820s.
Some items from the University of Texas at Arlington digital collection, including maps, photos and illustrations, are shared through the UNT portal at http://texashistory.unt.edu/.
You can obtain a lot more information in an article by Diane Smith in the Star-Telegram at http://goo.gl/hdx6h and in a video at http://youtu.be/TmHbN-YSX4M or click on the video player below.
