For those of you who are not aware of this resource, this is from their website - "The goal of Elephind.com is to make it possible to search all the world’s online historic newspapers from one place. We aren't there yet, but we are adding more newspapers every day."
Personally, I have used it and found it to be quite useful. You might want to visit their site and check out the About page. Expansion of the titles available are certainly always welcome, from any and all online historical newspaper sites.
Here is a summary list of the sources that Elephind makes available. I would encourage clicking the List of Titles to expand and see each and every newspaper held by each source and available for searching.
