Understanding large digital collections and learning new tools: The Texas Digital Newspaper Program Visualizations.
Mark Phillips & Will Hicks
As digital libraries continue to grow, they:
• Challenge existing infrastructure for searching and browsing
• Make it hard to communicate the size and scope of resources
• Have the opportunity to supply resources for those interested in the “long tail” of topics
Understanding and communicating the scope and scale of digital collections is important because:
• Allows for engagement with user communities• Introduces new opportunities for interaction• Helps promote underlying resources
The UNT Libraries Digital Collections currently has 429,591 items in 500+ collections/groupings.
These are published to the world as:
The Portal to Texas History
The UNT Digital Library
The Gateway to Oklahoma History
The Texas Digital Newspaper Program
• Promotes standards based newspaper digitization, presentation and access
• Empowers interested partners of all sizes to provide greater access to their local newspaper content.
• Newspapers are published on The Portal to Texas History and preserved in the UNT Libraries Digital Archive.
TDNP Statistics:• Over 1 million pages• 132,000+ issues• 3.6 million item uses• 1829 – 2013 date range• 596 titles• 102 counties• 131 communities

We creating several visualizations to help communicate this collection to users
We printed out two of them because they were rather huge
