"Major newspaper often offer reprints or back issues."
Perhaps younger readers have never experienced looking at microfiche of old newspapers in a library. Analog machines, not computers, but, if memory serves me correctly, the archives were far more complete than the so-called "tech" company-mediated, advertising-based nonsense what we have today on the www. And the analog fidelity was great.
Google ultimately failed to "organise the world's information" to the extent that it previously was organised by public libraries. Instead they turned finding public information into a game designed to support a massive programmatic advertising racket. The www has more volume perhaps than pre-internet libraries but 1. an enormous amount of it is garbage and 2. it is not organised for systematic browsing (leading to discovery) nor serious, methodical research. It is optimised for "clicks" and "views", selling ad services, not learning. There is no way to "browse the stacks" to see how this information is organised. It's all "secret". Imagine a public library that had to hide its operations as a "trade secret". Imagine that it tried to intermedite which stacks a patron will browse, for commercial purposes.
The point is that public libraries had extensive collections of newpapers and periodicals. The public could do serious research. But the www is dominated by advertisers and most of the information published is influenced by commercial motives. And it's all intermediated by a gatekeeper that sells ad services: Google.
If I want to use the internet (cf. www) for library research I still somtimes search library catalogs via z39.50 if the library's website is cludgy.
