I have written before about Richard Heaton’s online indexes of British and Irish newspapers. See http://goo.gl/Oj5ZM3 and http://goo.gl/0BAxVN for two of the earlier articles about this collection. Now Richard writes, “I have been maintaining a list of Titles of Digitalised Online British and Irish Newspapers. Whether available Free, by Subscription, or Pay to View. There are now over 2,900 references.”
Richard Heaton’s is an INDEX, not the images of original records. However, every entry in the index does point to a newspaper image on one of any number of other web sites. This web site is the place to start when looking for British or Irish newspapers. The actual images of newspapers are a mix of free, by subscription, and “pay to view.”
