The Memory Hole: ” The Memory Hole exists to preserve and spread material that is in danger of being lost, is hard to find, or is not widely known. The emphasis is on material that exposes things that we’re not supposed to know (or that we’re supposed to forget).”
Unknown News: “The news you need, whether you know it or not. We try to spotlight news that hasn’t gotten enough (or appropriate) attention.”
Both these news sites monitor and record big news reports, and in the case of The Memory Hole, when a newspaper censors itself for some reason, they will take note of the original writing and how it’s been changed. For example, check out how the New York Times deleted mention of Police Snipers at a recent anti-war protest.
