Last year I treated myself to an £80 or thereabouts subscription to the British newspaper archive . I really hammered it for a year , and I'm still wading through all the stuff I downloaded . I wouldn't subscribe every year , but I got my value out of it last year , and it was very useful for searching for the ship movements of a Victorian ancestor as he sailed around the world. There is also an American one but I think that would be very American centric .
Membership of Findmypast gives access to the British newspaper archive, but by going direct it has a slightly better interface. However as a former IT professional, I thought the interface was about 15 years out of date. The search options were very limited compared to what I would have expected.
