The newspapers you already claim to have on your site
Such misleading information your system has about what dates are covered.
It says you have Cambridge Independent Press 1839 - 1950, BUT YOU DO NOT. Only the odd year after 1900.
Again, Cambridge Daily News 1889 - 1994 but not all years.
It is astoundingly annoying to realise that the reason I cannot find an item is that you are missing those years. Especially when I found so much on a free weekend at newspapers.com!
