The online English newspaper archives are locked down behind a paywall, but material was often syndicated widely (i.e. was pushed through a press syndication service, where any subscribing paper could run any of the stories or articles on offer at no extra cost). For the benefit of independent scholars and researchers, here are links to three free newspaper collections, useful for searching for syndicated material. The Welsh one is especially useful for the UK, as Welsh newspapers carried a lot of syndicated content.
Welsh Newspapers Online. 15 million articles, fast and easy to use.
California Digital Newspaper Collection. Freely Accessible Repository of Digitized California Newspapers from 1846 to the Present.
Library of Congress newspapers. Mostly to about 1923.
Doubtless family-history researchers will be aware of more, but these are the three big “go-to” ones I tend to use.
