why in the world is this being sunset i wonder
Social media is much more suited to spread propaganda.
Facts are not a thing the government is interested in now
The internet now exists and easily surpasses the value of this static publication.
To avoid pesky facts getting in the way of them attempting to re-write history, like in 1984 (the book).
I concur.
Also, it was paid for by US taxpayer dollars - the entire content should have been released somewhere for free, maybe even someone would have started up a new project to maintain it, for example, something under Wikimedia or some other nonprofit.
This wholesale elimination of valuable information and data owned by the public is so incredibly sad and damaging to our future.
Maybe we need a FOIA request to get the entire contents released to the public.
