Well, most libraries where I live/know have central boards / panels that decide those things -- not necessarily staffed by professional librarians (e.g. the state appoints members there from the academic community, etc., some are voted, etc.). There are also deals to get copy(ies) from each published work (by specific or all publishers).

Librarians do handle the organization and everyday operation, archiving projects, curated collections open to the public, etc.

What's the difference between Google removing a terrorist video from public view (they never delete anything), and a library having a book but the librarian not making it available to the public?

I mean, you rebut me when I say Google curates its own content, then turn around and say librarians are different, their duties include curating content.

Edit: How come people don't call Google some sort of evil censoring overlord when it comes to child pornography? You'll get the good ol' "I defend to the death your right to speak" when it comes to terrorist videos, but not child exploitation ones. Where are the people angrily demanding that google put child pornography back into their search results, out of a demand for freedom of speech for all? Why is that topic treated differently to terrorist recruitment videos?

Because most people act irrationally when it comes to related issues, and because other people (still a minority) don't want to be branded negatively by hysterical public/pundits.

One might as well ask where were the vocal proponents of black rights in 1920 Alabama?

Responding to your edit, some people might disagree with child pornography laws&policies but recognize that any protest will be branded as supporting pedophiles/hurting children and decide that they'd rather die on a hill upon which they have a chance of winning.
