Responding to expressions of interest from many quarters a database of two million pages of digitized and searchable 19th century British newspapers has just been made available for time-limited public subscription online here.
The database comprises 49 local and national titles from all parts of the UK. For example, the Ipswich Journal is available from January 04, 1800 to December 29, 1900. There's a full list of titles with the range of dates covered here.
You can search and view a snippet result for free, but need to subscribe to see full articles. The free snippet may be enough.
A 24-hour pass costs £6.99 allowing you to view up to 100 articles; a seven-day pass with 200 article views costs £9.99. That's not bad compared to the cost of a single document from TNA's Documents Online.
