Genealogy database site World Vital Records will provide “increased access” to the collection of NewspaperArchive.com, the largest online subscription newspaper database.

By “increased access,” World Vital Records webmasters mean they’re extracting vital information in newspapers dating from 1759 to 1923, resulting in half a billion records, and making it searchable on the World Vital Records site.

The first release of the NewspaperArchive.com data—40 million records—went up Aug. 27, and data for more titles were posted today. World Vital Records gives 10 days of free access for each site addition, so start searching.

After 10 days, databases are available with a World Vital Records subscription, which costs $49.95 for two years.

Find the data on World Vital Records’ Browse Databases page. For now, you have to search each title individually. You can search by name, place, year and keyword, and results are linked to (supersized) images of the original articles.

Update: Based on the comments, it looks like some are having trouble accessing the free newspaper databases in World Vital Records. To review: Each new database is free for 10 days after World Vital Records adds it. After the 10 days are over, you must subscribe to access that database.

To find the free content, use this link: http://www.worldvitalrecords.com/recentcontentlisting.aspx. Next to each database listed on that page, you can see how many days of free access remain.
