This post compiles a collection of sites that provide data, covering curated collections, data releases through Open Data movements or 'Data-as-a-Service' platforms. This collection has previously lived elsewhere on my site under the 'REFERENCES' menu but I have decided that I no longer intend to put energies in to maintaining this as an ongoing, comprehensive and up-to-date list. (On that note I can't guarantee that all links are live, active and current).

Rather than kill the page remorselessly I thought it would at least be worth sharing here as a form of permanent archive and just let it slowly, gradually decay in value over time.
