Well, we'd not heard of 'PressReader', sounds useful, but I'm not sure what "via the library" means. I didn't know I could make a 'virtual visit' to the Library, haven't been in it for years, though they do a good job.
Re paper circulations, I've said on here several times -- when folk talk about the naughty right-wing press -- that reader numbers have dropped like an anchor for 20+ years now.
There's a popular myth that the Press drives political preferences, but in fact the publishers know what their readers want, and try to supply it. Hence the same firm publishes the Mirror and Express, amongst others.
Oh, anyone wanting to TRY a paper that tries to help them a bit might trial the 'i', which provides different opinions about assorted topics (varies by the day), you can assess them and make up your own mind.
