Interesting. I wonder if libraries suffer a supply-chain risk and so avoid taking contributions from (non-vetted) individuals? I imagine that over time a library gets lots of offers to take "important works of literature" from cranks, and perhaps they've developed this culture to protect them from that. Pure speculation, of course.

Libraries typically don't even accept print books or CDs/DVDs. If there's a donation bin outside it probably isn't even theirs. And if stuff actually winds up with them, it just gets sold off so they can purchase material via vetted channels.
