Have just noticed, I'm pretty sure it was since yesterday, that the Gale archive (which is accessible from some libraries) has expanded the newspapers covered. Not sure by how much, but they used to only cover the Birmingham Post from Birmingham, but now also include the Birmingham Journal and the Birmingham gazette. Still some gaps in each (for Birmingham post it is 1896-99), and of course not as good as the paid-for British Newspaper Archives, but better coverage than before. Presumably other areas coverage is also better
