This beta site, last updated on 25 August 2013, looks very useful indeed to those working with 19th and 20th century British and Irish newspaper sources. It has now been bookmarked on HFL Delicious along with many other newspaper resources.
Richard Heaton’s Index to Digitalised British and Irish Newspapers Online (Beta)
The website is a list of all the titles in all of the Digitalised Online British and Irish Newspapers that Richard Heaton, a researcher, is aware of and which, he says “may be a helpful guide to identify whether a title is available online and, if so, what dates could be available and where you can locate it based on the data provided by the various sites (see link below). The Lists are split England (excluding London), London (which splits between Local newspapers and National Titles), Ireland, Scotland, Wales, Channel Islands, and Isle of Man. They are sorted by County and then Town except London (which being a very large file) which I have chosen to sort by title (which means titles from the 17th Century could be next to those for the 20th Century).”
