What is the earliest instance of a SciFi work describing a system satisfying the following criteria (basically a massive computer database coupled with the networking system to access it available to everyone)?
Database contains 100% of available knowledge (or as practically close to it as possible), necessarily including but not limited to:
All of that information can be queried out, possibly with some controls to satisfy privacy needs.
Universal access (e.g. practically any person on Earth can connect as a person, not just select few or limited by profession/organization). This one trips up many possibilities, e.g. H2G2 which arguably might fit the other criteria.
The precise implementation doesn't matter, some supercomputer, a super-AI, a whole planet ala H2G2 or a who-knows-how-it-works black box - doesn't matter. But it must satisfy the rules above.
The earliest one I can think of is from 1978, but it's in Russian (for those who care but can't guess, "BVI" - Big World Informatory - from Strugatsky brothers).
