This is a new digital newspaper resource. I didn't see any SC newspapers but it is a new tool and I think I will check back to see if they have updated the records. It looks like it will be a tool that combines all the digital newspapers sites. I found newspapers from Chronicling America and from digital projects nationwide. There are lots of nice search features. Below is the description from their web site:
"The Catalog of Digital Historical Newspapers (NewspaperCat) is a tool that facilitates the discovery of online digitized historical newspaper content from newspapers published in the United States and the Caribbean. NewspaperCat was funded by a grant from the George A. Smathers Libraries.
Search by keyword, newspaper title or by city, county or state to locate titles. From your search result, click on the link(s) to connect to the digital newspaper(s). In many cases, this content is keyword searchable, depending on the hosting organization.
NewspaperCat currently links to over 1000 full-text newspaper titles with a goal to include links to as many US and Caribbean newspapers with archival digital content as possible.. Plans are to expand the Catalog as newly digitized newspaper titles are located."
